schematic transfer between different versions

Faizan UL HAQ

Hi,

I found somewhere that dbWriteSkill command can be used to generate .il extension file for a schematic. This .il extension file can be loaded back to other versions of virtuoso to get the schematics back in other versions. 

I ran the following commands in CIW to generate .il extension file for my schematic


cvId = dbOpenCellViewByType("myLib" "myPcell" "schematic")
dbWriteSkill(cvId "/tmp/dumpFile.il" "w" "6.1")

However, i don't know how to load back this dumpFile.il back in virtuoso as schematic. guidance required.

  • Actually i have to copy design files from one CMOS process design kit to another CMOS process design kit.  My original intention was to create a skillcode of all schematic design files using dbWriteSkill() command in one design kit  and then try to edit the code in such a way, that i replace the transistor models with second design kit models. Later on i import the edited code back to cadence.  In this way, i was thinking that i will not have to change manually the transistor models (which can take long time). However, as you suggested this is probably not the right way.      

    A more time consuming way to do this design transfer from one CMOS process design kit to another CMOS process design kit will be to copy the design library and then change all the transistor models in each schematic manually. Is there is any way, i can change all transistor models with just one command in skill language.
