As a custom i am not very satisfy with foundry provide PDK, I want to do some customization, using different transistor geometry and different device model, Does anybody know how to build my own PDK based on foundry process ? Until now I know, several component are required , parameterized cell builded using skill language, device model , does any body know what other requirement do i need? and how to put them together ?
Building a PDK from scratch can be quite a lot of work. You need to do:
If you have no experience of this, you may be better off talking to somebody who does - for example, Cadence Services.
In reply to Andrew Beckett:
Thank you for your reply. Now how to build following item:
2 .Symbols for each primitive component, and stopping views for each supported simulator
3. CDF for each primitive component, describing each of the supported parameters, and also how to netlist each component to each simulator that you are supporting.
Do you know?
In reply to alexyu:
The symbols are often copied from those in analogLib; same for the stopping views. This may be automated using the SKILL function dbCopyCellView().
The CDF is also often based on similar components in analogLib - but in practice the precise parameters will depend on both the device models and the parameters for your pcell. A good way to start is to use the cdfDump() function to dump the CDF from an existing component, and then you'll get the SKILL code needed to build the CDF - you can develop it from there to fit your needs.
Thanks for your help. I will follow your suggestion for next few days.
