Below is the verilog coding and verilog netlist for simple flip flop

***************************************************************************************************************************
module ff (clk, rst, d, q);
input clk, rst, d;
output q;

reg q;

always @(posedge clk)
begin
if(rst)
q = 0;
else
q = d;
end

endmodule

module ff(clk, rst, d, q);

input clk;
input rst;
input d;
output q;




DFFTRX1 q_reg(.D(d), .CK(clk), .RN(n_3), .Q(q));
INVX1 i_8(.A(rst), .Y(n_3));
endmodule

*****************************************************************************************************************************[

above is the verilog netlist after optimize with artisan library. i am using .alf file.Eventually, when i import to icfb it has statement :


Verilog defination for module DFFTRX1 was not found. using lib 'silterra18' cell 'DFFTRX1' view 'symbol' as its symbol


Verilog defination for module INVX1 was not found. using lib 'silterra18' cell 'INVX1' view 'symbol' as its symbol

So, because this error i cannot use the verilog xl to do gate level simulation. How can i define the module?

If you only want to run gate level simulation by verilog-xl, it's not necessary to import netlist to icfb. You can run verilog-xl directly. For example,

verilog $verilog_netlist -v $verilog_library -y $verilog_library_path

$verilog_library can be found in which library installed.
