Spice netlist from Magma

Hi

Using Magma command
export verilog netlist $library lib.v
I obtained the verilog netlist of all the standard cells in the library.

In the same way I tried
export spice netlist $library lib.cir
But could not get the spice netlist of all the standard cells.
-----------------------------------------------------------------------------------
=== PROBLEM ===
Model not found /cl013lv
while executing
"export spice netlist $lib lib.cir"

-----------------------------------------------------------------------------------

Can anybody help me with it ??

Sounds like you don't have spice/transistor level library to use to convert the gates.

Hi,

I assume that you are using Magma for place & route.

for logic or functional data part, you might have read the verilog as input during previous stage of Magma design flow, the Place & route tool was able to dump the top level verilog netlists.

but for physicals you might have read in a gds2 / DEF / LEF as input. you need to extract the device & its connectivity from physical database. This is the job of a extraction engine like calibre / hercules - starrcxt / assura / PKS / quartz and not a place & route engine.

I use V2LVS(Calibre) command to convert the verilog file into the Spice file.. I dont know whether it is possible to export the Spice file directly from the P&R tool...
