Creating vector variable in ADE XL to configure Verilog-A module

RaffaeleUdS over 1 year ago

Hello,

I would like to send a vector through the ADE XL variable sets to a Verilog-A module.

I have a parameter set in the Verilog-A as:

electrical [3:0] B_RCH;

parameter integer RCH_b[3:0] = {0,0,0,1};

And each bit configures an output bus of the module like so:

generate j (3,0) begin
V(B_RCH[j]) <+ (RCH_b[j])*V(VDD);
end

Now, I can set the parameters successfully in ADE L "Design Variables" setting:

RCH_b | [1,0,1,0]

Nevertheless, if I try the same in ADE XL this doesn't work.

How can I achieve this?

Also, is it possible to run different simulations varying the vector with a CSV file?

I think you might just need to make the variable value strcat("[1 0 1 0]") in ADE XL instead.

Not really a way to vary the vector with a CSV file (since you can't do that in general with ADE XL), but you could define a CSV file for a set of corners each with a different value of the vector (with the strcat() around it) and then import that into the corners tool. Note I have not tested this so it might not work - but I think it probably should if done correctly.

BTW, you should be using Assembler rather than ADE XL since ADE XL is obsolete.
