lvs and cdl netlists

Hi all,

I am having terrible trouble trying to do a simple lvs on a standard
cell.
I have an inverter instanciated in my test schematic. I have a cdl
netlist
supplied for this inverter. It will not LVS. I have included the
netlist under the
netlisting options on the top of the assura form - I am not sure if it
is even being used
and I get an error saying lastSchemticProperty was not set on my
testbench schematic.
I don't want to use block boxes. We have a cdl with transistors so I
really want to compare.
Someone must have encountered this problem before....any ideas/help?

regards

I guess you have created yourself a symbol for the inverter.

You need to create an auLvs view for it, so that assura treats this component as a leaf cell when
netlisting. If this view is missing, it'll try to switch to another view, eventually it will fail
because it cannot find a switch view or finds a wrong one (symbol in your case, i guess).

To create auLvs view, copy the symbol view to auLvs. You may need to edit the CDF simInfo.

Hi Stephane,

No I had the symbol but created a spectre view so that I can simulate
it in artist with the cdl netlist converted to spectre format. I have
tried to update the simIfo section with the pin sames but I guess I
need some information regarding the netlsitprocedure etc. Now I have
the following errors:

Running Artist Hierarchical Netlisting ...
*Error* Cell: INVX20 in library: KK_TEST is missing a simInfo
section in it's CDF for the current simulator.
*Error* artIsCallablep: argument #1 should be either a string or a
symbol (type template = "S") - n

I have emailed cadence support but I think they are away for Easter
hols...Anyone got any idea what
to put in the siminfo section..

For LVS, try removing symbol from the "view list" on the netlist
option.
