AMS connect module AICM
Mar 07th, 2007, 1:09am
 
Hi All,
(AICM = Automatically Inserted Connect Modules)

I am using AMS for the first time, after I used for a lot ADMS from Mentor.

In my design I have 2 different voltage supply 1 for 1V8 and the other one at 3V0, unfortunately
I have many 3V0 digital cells spread everywhere in the design.

When I do the ncelab step I can specify with the command
-discipline logic connect_lib.ConnectRules1V8. to change the default logic disciplines
I use the command -scope_discipline 'inst-top.<ist_name> -logic3V0' connect_lib.ConnectRules3V0

Any body knows How I can specify to AMS tool in one shot all the 3V0 Digital library elements
so AMS can do the AICM; without I need to specify
all the istances name in my design, where I need
to change the L2E default connect module?

Thank you in advance
Ros

Let's say your digital lib is mylib_3v  and you want to define the discipline "logic3v0" for whole cells under this lib , you can add following in your ncelab command

ncelab  -scope_discipline "lib-mylib_3v- logic3v0"    .....

Instead of define cell by cell or instance by instance ... This allows you to define  customerized discipline in one-shot for whole lib

BTW, you can also use AMS-ADE to define discipline on  lib/cell/cell-term/instance-term/net via Composer. In order to do that ,
1. Choose ams simulator in ADE
2. After step 1, Composer will show "AMS" in the tool bar
3. Composer -> Tool bar "AMS" -> Default Disciplines Selection -> Library ...

Hope this helps ..
