verilog to netlist translation error , calibre v2lvs

Discussion created by eng.marwa_ahmed on Jun 26, 2010


i'm in an asic project .
we use tsmc 090 standard cells.
we generated rams using artisan !
we use synopsys design compiler (synthesis)
first encounter(layout)
calibre(lvs , drc etc)

to perform post layout simulation on modelsim , and verilog to spice netlist translation using calibre v2lvs , we enter the verilog file generated by the first encounter , and the standard cells verilog library, but we have a problem with the rams :

Warning: no module declaration for module ram_128_3 first encountered in module DSR_artisan_3_0

and the module DSR_artisan_3_0 reports a lot of errors in the form :
Warning: DSR_artisan_6/DUAL_SRAM calls array of unknown dimension DB in undeclared module ram_128_2

also the pads outputs errors in the form :
Warning: top/Data_in_PAD insantiates new port C in undeclared module PDC0204CDG_33
and :
Warning: positional call to undeclared module PCORNERG_33 in top - pin order will match verilog call.

no ideas ?
consider it as if u are making post layout simulation (it is the same idea)
how to resolve that ram problem ? also pins of the pads undefined ?

thx for your help
