Fetching pin order for spectre netlist

What is the most reliable way(through skill) to fetch the pin order for a given schematic/symbol that would be generated by a spectre netlister?

If I fetch the values using

almGetTerminalList(lib cell ?tool "spectre")

there are missing pins(addition/deletion) compared to the original symbol.

I guess(not sure) this is because the pins were modified in the symbol manually[ without using create cell view from cell view]

I need the port order property because I am trying to hack and define this existing subckt

Thanks

Hi,

From Cadence Support: SKILL: Update the pin or port order or portOrder property of symbol view as per verilog view to avoid out of sync warnings during cross view check

I think that the following command should do the job:

(geGetEditCellView)->portOrder

Cheers

Hi Aurélien,

The portOrder on the cellView (if present) is not used for CDF-based netlisters such as the Spectre netlister. Pretty much the only thing that will use it is the Verilog netlister and the "digital" CDL netlister (which is not used for most flows).

Hi Shankar,

I don't think there's an API to get the actual terminal order used during netlisting (that I can think of). It's complicated - because it will try to use the CDF termOrder (which is the API you were using) - but if that's inconsistent with the actual terminals on the master and switch view then it will be ignored and a default order is used instead.

I suggest. you contact customer support - maybe there's an API to do this that I'm unaware of off the top of my head, or maybe one could be provided.

Regards,

Andrew
