Skill command for adding Verilog parameters to the CDF's.

Hi Ivick,

You should be able to save the view, or create a symbol from this view and the tool should automatically scan the view for ports and variables which will then be added as cell CDF. The Create -> Cellview From Cellview menu may help here.

Best regards,

Lawrence.

Hi Lawrence,

The symbol already exists and no change is needed there, the idea is using a skill function in order to accomplish this task because it will be more than 200 cells for which we should perform the task manually.

I have already updated their Verilog view but their parameters were not added to the CDF's after I checked out the updates, then this parameter will not be available at schematics when someone instantiates any of those cells.

Do you know a skill function that adds the corresponding Verilog parameters to the CDF's (the aim it would be not open any view manually).

Thanks and regards,

Ivick.

Hi Ivick,

I think the function might be ahdlUpdateViewInfo() - look for the documentation of it to make sure.

Lawrence.

Hi Lawrence, 

I already tried the ahdlUpdateViewInfo  (the function returns 't') however the parameter is not added to the CDF's . Is there other function that adds  the corresponding Verilog parameters to the CDF's?

Thanks and regards,

Ivick.

Hi Ivick,

The documentation said this: "During the update, ahdlUpdateViewInfo, parses the Verilog-A or SpectreHDL modules that define the specified cellviews, issues any necessary error messages and updates the cellview CDF information."  If you are not getting the CDF updated then I'm not sure what is going on, perhaps file a service request with Cadence?  Maybe it only works for Verilog-A and ignores digital Verilog

I'm guessing now, but what about schInstallHDL() ?  I don't know if there is a SKILL API for importing digital Verilog, I could only find impHdlDisplay()

Best regards,

Lawrence.

Lawrence, Ivick,

The function for digital verilog (and Verilog-AMS) to re-analyse the view would be vmsUpdateCellViews. However, for digital Verilog, I don't think it updates the CDF because the support for CDF parameters with Verilog textual views is a bit limited (this is a consequence of the Verilog netlister traditionally being a "digital" rather than "analog" netlister, and it was the "analog" tools that generally deal with CDF).

I would suggest you contact customer support.

Andrew.

Hi Andrew,

Good news! I decided to give a try to "vmsUpdateCellViews" and it did update the CDF's by adding the Veirlog parameters, just as I was looking for (data.dm checked out previously to be writable).

Thanks a lot!

Ivick Guerra.
