CDF re-creation

[Johannes N Blouwer]

Hi All

I have a design that started as another chip. It was extensively edited
over time and as a consequence the CDF data for the symbols are now wildly
out of step with the schematic.

Is there a way to re-create all the CDF data for the symbols?

TIA
JNB

You could use cdfDump() (see cdfuser.pdf) skill function on each
modified symbol in your old schematic , then edit the file and change
the target library name and then load it back into CIW with the load()
function. That way you also have a backup of your symbol cdf
modifications. (Is also a nice way to perform mass changes to cdf for
many symbols.)

I'm not exactly sure what you want-- re-create the CDF data from
what, exactly?

If what you want is to re-enter all the CDF data for a library
of symbols, all at once, without having to click your life away
in the CDF GUI, use cdfDumpAll(), e.g.:

cdfDumpAll( "devices" "devices_cdf.il" ?level 'base )

This dumps a single SKILL file for the entire library,
which you can then edit and re-load.

Hi,

You could use the artGenerateHierSymbolCDF()
function(eg.use artGenerateHierSymbolCDF(geGetEditCellView())
in the CIW for interactive CDF update of the currently open
schematic). Hope this solves your problem.

Thanks for all the suggestions. This one seems to be the closest to what

I want to do.

Thanks all
