Title: Efficient way of Defining MACROs(Directives) Globally
Post by Dipankar on Jul 7^th, 2009, 6:58am

Dear Experts,

I am new to AMS Designer. Curently I am facing an issue of globally defining MACROs in AMS. Let me first tell you the flow I am following. Please let me know if something is wrong.

Flow : Artist based AMS ( not the Hierarchy editor Plug-In)

steps : First, I verilog-in the RTL library (It's a hierarchical one) from CIW. In RTL library my TOP .v contains definition of the top module , many MACROs defined by `define statement and many files included by `include statement. Through the Library Manager I can see that all the modules/cells have functional view and symbol view. But the MACROs and `include are missing at the top.

2nd, I create config view of my TB and I can see all the verilog modules (except the modules with 'celldefine) used in my design at HE . so far so good.

3rd, Now I need to give AMS the MACRO values. I provide MACRO info like this : Simulation->Options->Compiler-> MACRO : MACRO name, MACRO value. It works for one macro. But I have a long list of macros. Currently I give the mostly used macro info there and add `define XXX for the others at the respective cells.
But Can you suggest a better soln. for global definition ? I also tried to define these macros at the top but without any result.

Dipankar,
I've done that sort of thing by defining the macros in the hdl.var file. I don't recall the syntax and don't have access to Cadence tools while I'm between gigs so I can't give you an exact solution but I hope this directs you down the correct path.

Dear BOB,

Thnx for the hint. Actually I listed all my `define from a xxx.v and included that xxx.v from ADE->Simulation->Option->netlister. Looks like working fine.
