viewing internal signals

I have created a test bench in order to run my simulation... basically I have a module and it only takes a clock as an input... how can I view the internal signals of that module?

 

 

module SCDP_tb();reg Clk;always begin Clk <= 0; #10; Clk <= 1; #10;endSCDP singlecycle(Clk);endmodule

 

Here's the module it self:

 

 

module SCDP(Clk);input Clk;wire Zero, Sign;wire RegWrite, MemRead, MemWrite, Beq, Bne, Bgtz, Blz, Bgez, Bltz, BranchMuxControl, BranchVal, Shift, HIWrite, LOWrite;wire [1:0] RegDst;wire [1:0] PCSrc;wire [1:0] ALUSrc;wire [1:0] MemtoReg;wire [3:0] Type;wire [4:0] ALUOp;wire[31:0] A4ALURes;wire[31:0] ReadData;wire[31:0] ReadData1;wire[31:0] ReadData2;wire[31:0] ALUSrc1;wire[31:0] ALUSrc2;wire[31:0] ALUResult;wire[31:0] pcinp;wire[31:0] pcout;wire[31:0] SignExtd;wire[31:0] ZeroExtd;wire[31:0] SLRes;wire[31:0] AddRes;wire[31:0] Instruction;wire[31:0] WriteData;wire[31:0] JumpOutput;wire[31:0] BranchMuxRes;................................................endmodule

 

 Problem is, how can I view the signals inside SDCP? Such as Type, JumpOutput, etc..etc.. all I can see in my ISim is the Clk:

 I can't see other signals besides the Clk, I want to see some other signals inside the module...

Hi,

 

When looking at the screenshot, it looks like you dont have all the object types enabled.

 

Under simulation objects for SDCP_tb, can you ensure that all the buttons are "selected". This should display all the types of objects in your design.

 

Hope this helps

 

Thanks

Duth
