Since the menu option for VPCD has been removed in IC614, I want to use VPCD from command line but I can not generate a cell which I have synthesized. When running from the dropdown menu in IC, the Configuration option lets you choose which library the generated cell is created in (_psmsChooseLibForm->_psmsLibNameStrField->value = "lab2" is what shows up in virtuoso), how can I set this via the command line? vpcd -h does not give any clue, nor do the files in ~/.vpcm_datdir.
Parts of the VPCD environment are in SKILL context files, so it's more than just being able to run from the command line.
In fact VPCD is also no longer in the MMSIM72 stream (VPCD was End-of-lifed in 2008).
So realistically you should use a version of both IC and MMSIM where it is available (i.e. IC613 and MMSIM71).
In reply to Andrew Beckett:
So if I use IC613 with setenv DD_USE_LIBDEFS NO, I shouldn't have any problems with the libraries being updated when I go back to using IC614? BTW has MMSIM72 been released?
In reply to tkhan:
That's right. In fact you shouldn't have a problem anyway, because it always writes cds.lib - it was just a matter of whether lib.defs was being created by some other process or manually. But I'd probably go for DD_USE_LIBDEFS set to NO anyway.
MMSIM72 is released and is on downloads.cadence.com (it was released over the last weekend).
For anyone who's interested, it looks like inductors generated by VPCD can't be used with MMSIM72 (pehaps with some environment tweaking it could).

Opening a PCD layout yields "pcellEvalFailed", I didn't try the layout_flat view though.

I suppose I could set CDS_VPCD_HOME to <MMSIM71_HOME>/tools/vpcd, but mixing MMSIM71 and MMSIM72 doesn't seem like a good idea.
VPCD is not supported in MMSIM7.2 . It was EoS (end of sale) a year ago. MMSIM7.1 is the last version it's supported in.
It is also not supported in IC6.1.4.

In reply to Tawna:
Hi,I was aware of VPCD being EOL since last year, looks like this is the final nail in the coffin. I'm going to try swapping the layout and layout_flat views, if that doesn't work I'll do as Andrew suggested.
