netlisting

Dear greywanderer,

I have a cell name "block" with a layout, schematic and symbol view in the library. I instantiated this in a schematic and the netlister netlists this cell as "block_schematic". Why does this happen and is there a way to prevent this from happening?

There are a number of conditions that will result in the netlister modifying the view name in the netlist from the expected view name. You did not mention if you are using the Hierarchy editor (config view) or just a schematic and hence I'm not positive which might be responsible in your case. Common reasons are outline in the support article at URL:

If you have the same cell defined in two different libraries and using a config view, you might review the various conditions that can result in the added suffix explained at URL:

In some cases, if you do a Netlist->Recreate, it may remove the "_schematic" suffix from the netlist.

Thanks Shawn and Frank.

Would it be ok to set hnlRegenerateCellNames in the cdsinit?

The expected place to set this variable is in the .simrc file because that is read by all netlisters. However, since the spectre netlister is run in the foreground in Virtuoso (rather than a background "si" process), putting it in the .cdsinit should be OK too. If you were expecting it to work for the CDL netlister (I suspect you're not) then that wouldn't work normally as the CDL netlister usually runs as a background si process.
