Cadence, stupid question

Hi all,

I have a question for Cadence guys.
What kind of netlist is this (generated by LVS), and I mean what
standard (SPICE, CDL, etc..)?
And where I can find specs (pdf files) for this netlist (in case I want
to make a parser...)

t 4 Outp1 output
t 5 Inp1 input
t 2 Outp output
t 7 Inp input
n 1 gnd!
n 0 vdd!
n 2 /Outp
n 4 /Outp1
n 5 /Inp1
n 7 /Inp
; nmos Instance /M2 = auLvs device Q0
d nmos D G S B (p D S)
i 0 nmos 4 5 1 1 " m 1 l 600e-9 w 900e-9 "

Best,

To me it looks like a netlist genrated by Diva.
If so this is a Candence internal format and not
an industry standard like Spice etc.
Best would be to have a look at the Diva Documentations
which are comming with the software, Diva reference manual etc.

It's Diva's own syntax. I don't think it is documented, but it's in a pretty
obvious format. Why would you want to write a parser? (t defines a terminal, n a
net, d declares a device, and i is an instance of a predeclared device).

Regards,

Andrew.

This is the Diva LVS internal format. There are no specifications since
it is not intended to be used by anything but Diva LVS. Use it for any
other purpose at your own risk.
