hi
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 encounter 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
