Converting a VHDL code to VHDL-AMS for simulation in Analog Design Environment.
May 31^st, 2010, 2:46pm

Hi all,
I have a VHDL code which I have simulated in modelsim and also synthesized in Xilinx board. But Now I need to put that entire code (The top one has 3 sub-modules in VHDL) into analog design environment to test out the characteristics of the overall system with the other analog blocks.
This is the first time I am trying to simulate an HDL code in ADE, so have very little idea about the flow. So, I would appreciate a bit of hints on how should I go about it in terms of various tools flow. I am having IUS82 tool. I have read the Verilog AMS guide in this comunity and successfully simulated the components like Flip-flops, AND gates ADC etc, but I didn't find any example there where a chunk of VHDL code of considerable magnitude being compiled in VerilogAMS and incorporated in ADE.
I have attached the code for one of my modules as a sample.
Waiting desperately for some useful hints/insights/suggestions/guidance. �

Hmmm. That's
weird...

If you want to work the analog way: Import the VHDL code into your environment using File -> Import -> VHDL from the CIW. That will give you a library with the VHDL block. You can then instantiate the VHDL block in your schematic. If you have selected the proper connect rules (similar to Verilog-AMS or Verilog examples) you can run your simulation from either ADE or the Hierarchy Editor using the AMS plugin.

Just import your code (i.e. compile it) in the Cadence database. Cheers, Jerome
