Plotting frequency with time...

Frederic,

I used the local function with the lambda binding for years already. It is
not necessary to 'funcall' the local function. You can use the local
function as a normal function within a function.

So:

let((mylocalFunc)
myLocalFunc=lambda((arg1 arg2 ...) body...)
; and then call it as usuall
myLocalFunc( arg1 arg2 ...)
; or
test = myLocalFunc(arg1 arg2 ...)
)

Untested but I guess it will work, you can use again 'let' to define local
variables within the local function body (and define again local
functions!)

See the skill language user guide, 'advanced topics', 'assigning a New
Function Binding' to get an idea.

Frederic,

This is exactly what SKILL++ is for. I suggest you do it in SKILL++ rather
than trying to find a tortuous way of doing it in SKILL. In SKILL you can
assign
function objects to variables in let statements:

let((mylocalFunc)
myLocalFunc=lambda((arg list) body...)
; and then call them using funcall:
funcall(myLocalFunc arg1 arg2)
)

but in SKILL++ it's cleaner:

let((local vars)
procedure(myLocalFunc(arg list) body...)
; and then call them
myLocalFunc(arg1 arg2)
) ; let

For a quick intro to SKILL++ look at my article:

http://sourcelink.cadence.com/docs/files/FFF/199/skillpp.html

Andrew.

Hi guys, thanks for all the suggestions! I've talked to a bunch of other
grad students at other schools and this is a real problem with Cadence and
the Analog Environment. The license files were suspects. For now I'm going
to try out all the suggestions and see what happens.

A while back, there was a post about spectre (via ADE in interactive
mode) not using the new netlist when changing component values on the
schematic. The workaround was to use spectre in batch mode,
resulting in longer simulation load times when only changing variables
in ADE.

The fix:

Check to see that there is only one entry per license file in the
environment variables LM_LICENSE_FILE or CDS_LIC_FILE. ex:
CDS_LIC_FILE={path}/cadence_license
LM_LICENSE_FILE={path}/cadence_license:{other license files}
For speediest performance, unset LM_LICENSE_FILE. Even though the
docs claim that CDS_LIC_FILE has precedence over LM_LICENSE_FILE, we
found that the latter is still parsed when icfb loads.

The length of CDS_LIC_FILE/LM_LICENSE_FILE also affects how long it
takes icfb to load. In my case, there was an order of magnitude
improvement for the time it takes the CIW window to come up. Another
positive side effect is that ADE->Simulation->Netlist and Run (with
spectre) is be MUCH quicker.

The why:

The cause of netlist problem has to do with license checking causing
interprocess communication timing problems between spectre and ADE.
Depending on how/where one's environment variables are set,
LM_LICENSE_FILE or CDS_LIC_FILE may have duplicate entries for license
files. ex:


LM_LICENSE_FILE={path}/cadence_license:{path}/synopsys_license:{path}/cadenc

e_license:{path}/synopsys_license:{path}/cadence_license:{path}/synopsys_lic
ense

After much debugging, we discovered that Cadence spends time checking
through EVERY license file that is listed in the environment variables
even though the Cadence license file is listed first. This happens
for IC446, IC5.0.33 on both solaris and linux platforms.
The time taken to parse every listed (duplicated!) license file makes
many parts of cadence slow to load (spectre, icfb, ocean scripts)

This slowness is exacerbated if both CDS_LIC_FILE and LM_LICENSE_FILE
are set and a non-cadence license file which has many features is
listed multiple times (in my case, another tool with over 400
entries). I was waiting upwards of 20 seconds before spectre would
even *start running* after 'Netlist & Run' on a ~20 transistor
schematic (as a single user on a linux dual 3GHz cpu, 2Gig RAM
machine!). Now, the same simulation FINISHES in under 10 seconds.

I'm not sure why Cadence checks the other license files once it finds
its own. (or even whether this is a feature or a bug!)

Dee.

Hi Frederic,

This won't work even if you use SKILL++. The reason is because gePointQuery
expects a function name, and is evaluated in the global scope - so it wouldn't
find a locally scoped function.

The solution would be if it accepted a function object, as you say. The trouble
is that this function pre-dates when function objects were created by SKILL.
However, it could be retrofitted.

Log a service request, and this enhancement can be requested.

After reading it, I tried to use skill++ in this way:
toplevel('ils)
let(()
procedure(mythrowawayfilter(arg) ...)
...
gePointQuery( arg1 arg2 "mythrowawayfilter")
...
);let
resume()

But it seems my procedure does not "finish" properly, I still have a prompt of "ILS".

You can't put toplevel('ils) and resume() in code files - it doesn't work like
that. toplevel starts a new top level. The best way to have SKILL++ code is
to give the file a .ils suffix. If you just want to use SKILL++ for a smal
region of code, you can use:

inScheme(
let(()
procedure(myLocalFunc(...) ...)
...
) ; let
) ; inScheme

But that's not going to help here.

Call me stubborn,but...would foresee any problem with a letfun(arg1 argrest) macro that would unquote argrest and then do something-like
mapcar(lambda((f) putd(f nil) ) arg1)
?

But the putd wouldn't make it local. It doesn't work like that. Each symbol in
SKILL has a function slot, a value slot, and a property list slot. The value
slot is effectively a stack (which is how dynamic scoping in SKILL is
implemented). However, the function slot is a single global slot.

In SKILL++ you have the concept of environments, which contain variable
bindings. When you define a function, it has associated with it the lexical
environment in place at define time. Then when you call the function, it
restores the environment which was there at definition time, so variable lookup
is lexically scoped (this is rather an abbreviated definition). Functions are
stored as variables (in essence), so a function call just looks up the
function object in the variable with the same name as the function call, and
then calls that.

Andrew.

I'm sorry, but this doesn't work with SKILL. I don't know why you think it does.
I'm prepared to be surprised, but I can't see how this can work in SKILL.

With SKILL++, it would work (do you have a .ils suffix for your source files?).

From the manual reference you give, I assume you're actually doing:

let((myLocalFunc)
putd('myLocalFunc lambda(....))
myLocalFunc(args)
)

However, the putd() would not be storing a local function definition. As I
mentioned in a previous post, the function slot of a symbol is global. And
putd writes into the function slot, and so the function is global. In SKILL,
the function slot and value slot of a symbol are distinct.

Hi andrew, how should i define functions which
i only want to be visible inside another function?
whould i define them with let/setq or with

procedure( (myLocalFunc2 arg1 arg2) ...)

...
let( ( x y )
x = myLocalFunc1( 1 2)
y = myLocalFunc2( 3 4)
myLocalFunc1( x y)
))

You can put them inside a defmethod() or a procedure(), and
they will be local. Put here, they seem to be created locally, but they don't
seem to have the method or procedure's argument list in their
lexical environment though (I've not experimented enough).
I must admit, I never create local functions this way in my code, so I've not
really played with this form enough (except just now to try it out).

Or should I put the procedure definitions inside the let?
And should I declare myLocalFunc1 and myLocalFunc2
inside the let?

That's indeed what I would always do - put the procedure definitions within the

let. There is no need to list the procedure names in the list of local variables
for the let - this gets done automagically by SKILL++.

Or should i declare the variables myLocalFunc1 and myLocalFunc2
and assign their values with lambda?

defmethod( mymethod ()
let( ( myLocalFunc1 lambda( ( arg1 arg2) ...))
( myLocalFunc2 lambda( ( arg1 arg2) ...))
x
y )
x = myLocalFunc1( 1 2)
y = myLocalFunc2( 3 4)
myLocalFunc1( x y) ))

You can do this, but there's no particular benefit in doing so.

I suspect that if i put the procedure inside the function def
it is more computation intensive in that it redefines
the procedure everytime the function is called, but that
somehow the lambda is optimized. Is that true or are
they equivalent?

It does not redefine the procedure every time you call the parent method or
function.

You should be aware that you can't put defmethod() or defgeneric() within a
let() and expect these to be local - the CLOS aspects of SKILL++ don't entirely
mix smoothly with the scheme aspects - so you can't have local classes and
generic functions; these are always global.

Andrew.

Hi all, when I use Cadence, I will run a simulation, make a
change to
my
schematic, or simulation, and then do a new 'netlist and
simulate'.
Well, I
nearly went crazy the other day trying to find out why my changes
weren't
producing the changes I thought they should.

Cadence will go through the motions, perform a simulation, and
the
results
will not change. You can close down the Analog Environment,
restart
it,
and
run the simulation successfully. This is not the way things
should
be
though. Even adding another simulation such as AC will not
produce
any
AC
results if you started out running DC or transient.

So, any ideas on what is causing this problem? Again, if I
change
the
schematic and try re-running the simulation, it seems to be
running
the
old
one over again. I am checking and saving my schematic, and I am
creating a
new netlist...!

Do you check and save your toplevel schematic before starting
simulation?
Are you changing any referenced libraries?
Check the input.scs file in the netlist directory in your Project
directory to see if its date change.
Do you have any saved simulation data that accidentally get viewed
instead of your new ones?
Are you creating the netlist or are you recreating the netlist?

This does indeed seem to be the case. It tries primitives first. Also, models

Unfortunately that error message can be from almost anywhere.

It is caused by some code doing something like this:

sprintf(nil "testing 123 %s\n" myvar)

where myvar was nil instead of being the expected string. Since
printf/fprintf/sprintf is rather widely used in both Cadence and customer code,
and there are so many possibilities for this, it's hard to track down.
In an ideal world, error checking in the code would spot the problem
before it resulted in a low level error such as this, and report it
gracefully. However, in the real world, code does not always do all the error
checking that it should...

One approach to track it down is to do:

sstatus(stacktrace 20)

which will force an automatic stacktrace whenever such an error occurs - this
might reveal at which point it is failing, althought it may not help you as an
end user without help from Cadence (it might though...)

Hi Bob,

I don't believe there's a way of doing this with a public SKILL functions (I can
think of ways of doing it with private functions, but that's not going to help
you).

You can of course do this with OCEAN, as the run() function will by default wait
for the job to finish - or with distributed runs you can use the wait()
function, or you can run in blocking mode.

What are you trying to achieve here?

One trick you can do is to make the SKILL function one of your output
expressions (in the output pane), and so if you have the option to automatically
plot the outputs, it will be triggered at the end of the simulation ;-)

Adrian,

Assuming you're using Diva (I wish people would say which tool they are using,
since there are often alternatives. Here it could have been Diva, Assura,
Dracula or non-Cadence tools like Calibre), then one thing you could do
is to ensure that all your abstract views have a cellView property called
ivIncludeValue, with a value of (say) 2. Then run Diva DRC (flat) with the
inclusion limit set to less than that value (say 1).

Then it will omit checking any of the cells with an ivIncludeValue greater
than the specified inclusion limit value, and you'd just be checking the
routing.

While Andrew's solution does work, it does not check for problems
between the routing and the cell content. Every layer in the abstract
view should have keepout shapes that represent the area occupied by the
internal shapes without actually being those shapes. This lets you check
for DRC violations between the cell and the routing.

As for parasitics, you can have the abstract view switch to a schematic
or symbol view during netlisting for the simulator. Assuming the
schematic or symbol have the appropriate information, the simulator
should have everything it needs without any annotation on your part.

Then it will omit checking any of the cells with an ivIncludeValue greater
than the specified inclusion limit value, and you'd just be checking the
routing.

hi...

How can I force the Left Mouse Button to be in a mouseAddPt() mode, from my skill
code.

I optimistically called mouseAddPt() but it doesn't do the trick.

F.ex after I select a menu item it's mode switches to mouseAddPt().
After I click once in window it goes back to mouseSingleSelectPt() mode.

I want to switch it to mouseAddPt() without selecting the menu item again.

Is this possible ????????????????????????????????????????

Not exactly what you ask but you can try these:

-options->editor "modal" on
-right click to repeat last command

Hi,

not sure at all what you're willing to do.

mouseAddPt() is a function you set as a bindkey.
When bound to a key, pressing this key acts as
pressing the mouse button. "staying in mouseAddPt
mode" doesn't make any sense to me, as you have to
move the mouse to a point before calling mouseAddPt
to input that point.

if you want to collect points user enters with the
mouse, you should use enterPoints() instead or any
other enterFunction.
