verilogin problem: modules are imported twice

 Hi All,

I'm importing some verilog files into  dfII library to generate a schematic to run a transistor level simulation.The library for standard cells are created first. When I use verilogin, it can proceed without errors but there is a weird problem, it will place each module twice, one with proper connections and one without any connections.

For example, following is a simple verilog file, containing only one inverter.

module test (A, B, VDD, VSS);

input A;

output B;

input VDD;

input VSS;

INHDV1 inv1 (.VSS ( VSS ), .VDD ( VDD ), .I ( A ), .ZN ( B ) );

endmodule

INHDV1 is a standard cell and it has ports VDD/VSS/I/ZN. But the imported schematic has two inverters, where one connects to VDD/VSS/A/B correctly, and the other has no connections at all.

I tried some options in verilogIn form and read the document. No clues. We are using IC5141usr6.

Could anybody give some suggestions?

Thanks,

 Howel

     Hi Andrew,

    Very curious, the problem is gone after I switched to IC5141user5. Actually I'm using only ihdl from ic5141usr5 since this time I tried to use command line. After preparing the ihdl_files needed, I specify the path to call ihdl residing in 5141usr5, now everything is ok. Don't know why.

    The version for ihdl in 5141usr5 is 5.1.0 06/20/2007, and for 5141usr6 it's 5.1.0 10/28/2008.

    And ncvlog's version is 8.20-s024. ( But in ncvlog.log, it said 5.50-E115. )

    Perhaps there are some compatible issues in my environment. 

    Thanks a lot,

    Howel
