Netlisting failed with multiple Verilog-A blocks

ywyc

Hello,

I have encountered netlist errors when trying to simulate circuit which has two simple Verilog-A blocks. Each individual block can be nestlisted successfully. However when I put them in the same schematic, there are errors. The error messages are:

"ERROR (OSSHNL-524): Netlisting failed as function hnlNetNameOnTerm was called with a non-existent terminal name on current instance 'I1' in design 'RF14/cal_logic_decod/schematic'. Ensure that argument to this function is a valid terminal name and netlist again.\n\n"
and many more of the same thing...

The two verilog-a blocks are defined like

module A(B_in, T_out);

input [4:0] B_in ;
electrical [4:0] B_in ;
output [15:0] T_out ;
electrical [15:0] T_out ;

endmodule

module B(clk, vin, vout);

input vin, clk;
output [4:0] vout;
electrical vin, clk;
electrical [4:0] vout;

endmodule

Please advise, thank you.

  • Sounds rather odd. Which version of the IC tools are you using? (Help->About in the CIW will tell you the subversion). Assuming that the symbols match the VerilogA views, it may just be a matter of check-and-save of the schematic containing the two instances. However, I'm guessing. I suspect that (assuming this is in some vaguely recent version of the software, and it isn't fixed in a later version) you will need to contact customer support so that we can actually see the problematic data, as guessing the problem here might be hard as I'm sure it is specific to your data, as nothing you've described here is terribly unusual.

    Regards,

    Andrew.
