Hello,

I want to build a ideal circuit by cadence, which the voltage Ux is defined by dc analyse as following:

1. for Uin<1V -------> Ux have to be Uin+2V.
2. for Uin>=1V -------> Ux have to be 3V

Which ideal component in Cadence can I use to define Ux?

I would be thankful for your reply.

Best regards

Sarah
 

This would be very easy to do with VerilogA.

- - - Updated - - -

`include "constants.vams"
`include "disciplines.vams"

module YOURMODULENAME(in, x);
input in;
output x;
electrical in, x;

analog begin

if( V(in) < 1)
V(x) <+ V(in) + 2;
else if(V(in) >= 1)
V(x) <+ 3;

end
endmodule
 
Hello,

thank you very much for your reply.

I have done it and wanted to create it symbol (Library Manager -- file/new/cell view), but it is emty.


Do you know how can I create its symbol for cadence schematic?

thnaks again,

Sarah
 

You have to create the verilog file first.

file-> new -> cell view
then choose verilogA
paste the code
save and close

If there are no errors cadence will tell you that there is no symbol yet and asks you if you want to create it automatically.
