Hi all,

Can anybody tell me how to set up the ams simulator??
May be I'm doing some mistake in the ams setup.  I was trying to run a simple invverter, having verilog view.


Here is how I set up the config  view:

Hierarchy Editor -> Write Schematic in the field View (name of the window is New Configuration) -> Choose AMS in Use Template

What I see after this is:
Library List: basic analogLib
View List: verilogams veriloga behavioral functional schematic symbol
Stop List: Symbol

Don't know why it does not choose verilog for the inverter!!!
As  expected it gave an error saying..

*Error* <ACE setSimParams>  Failed to read  /home3/rajdeep/simulation/inv_test/ams/config/netlist/netlistHeader"

AM I MISSING SOMETHING IN THE SET UP?

Hi Andrew!!

" You say that it does not choose verilog for the inverter - how do you know that? What views are present under the inverter? "

3 views are available for the inverter..layout, symbol, verilog.
Well, in the hierarchy editor I have seen it choosing the symbol view for the inverter. That's how I know.

Is ther a great deal of difference between setting up spectreVerilog and AMS?
Where can I get the AMS documentation?

You do not have verilog in the view list, so the only view that it will pick automatically will be symbol. So you have two choices - either add verilog into the view list (in front of symbol), or go over the view name for the inverter cell and use right mouse->view to use, and pick verilog.

Using the hierarchy editor for view selection is the same regardless of whether you are using SpectreVerilog or AMS.

That ACE error looks to me like something coming from a Nat Semi flow. I've seen this before:

     \o <ACE> Adding Spectre flowchart step "ACE_setSimParams"

and so I believe it is a local customisation to the spectre flow. Please check with the supplier of your design environment.
