CIW > File > Import > Verilog... fails to create schematics (portOrder property?)

Hello

 I try importing the final verilog (.v) file generated by SoC encounter so I can do LVS for a mixed signal design, but ihdl.exe doesn't generate schematics. The beginning of the log file says (scgp is the digital library name in icfb):

@(#)$CDS: ihdl.exe version 5.1.0 12/16/2007 23:32 (cicln04) $ Fri Feb 5 15:20:53 2010

Compiling files:
1. /nfs/guille/moo/JAZZ_EXTENDED_LIBRARIES/verilog/src/scgp.v
into IR library SYNTHESIZED_STREAMIN_05
VerilogIn: *W,156: Rejecting lib 'scgp' cell 'nand3x1' view 'symbol' for module 'nand3x1' because terminal does not exist for a port in portOrder property.
VerilogIn: *W,31: Module nand3x1 in comparator not defined.Module comparator will be imported as functional.
VerilogIn: *W,31: Module nand3x1 in comparator not defined.Module comparator will be imported as functional.
VerilogIn: *W,156: Rejecting lib 'scgp' cell 'invx1' view 'symbol' for module 'invx1' because terminal does not exist for a port in portOrder property.
VerilogIn: *W,31: Module invx1 in comparator not defined.Module comparator will be imported as functional.
VerilogIn: *W,31: Module invx1 in comparator not defined.Module comparator will be imported as functional.
VerilogIn: *W,156: Rejecting lib 'scgp' cell 'nor2x2' view 'symbol' for module 'nor2x2' because terminal does not exist for a port in portOrder property.
VerilogIn: *W,31: Module nor2x2 in comparator not defined.Module comparator will be imported as functional.
VerilogIn: *W,31: Module nor2x2 in comparator not defined.Module comparator will be imported as functional.

and on and on. First I tried generating the final (.v) file from encounter with:

 saveNetlist -phys final.v -excludeCellInst {filler1 filler4}

but this made ihdl.exe complain about having the wrong number of pins, so I use:

  saveNetlist  final.v -excludeCellInst {filler1 filler4}

The (.gds) streams in perfectly. I can't find any documentation for ihdl.exe

Am I doing something wrong?

    Hi Skyler

    The manual for verilog-in is located at $CDSHOME/doc/verinuser/verinuser.pdf. I guess it might be due to power pin mismatch between the symbol and the verilog netlist. E.g. symbol contains VDD and VSS pins but not the verilog netlist. 

    Best regards
    Quek
