Title: Envelope Analysis is available in Cadence AMS ?
Post by pancho_hideboo on Feb 14^th, 2009, 5:28am

I have some questions about AMS simulation of Cadence.

Currently I can use Verilog-AMS models in cosimulation between Envelope Analysis of Agilent ADSsim and Cadence NCSim.
In next release Agilent GoldenGate, I can use Verilog-AMS models in cosimulation between Envelope Analysis of Agilent GoldenGate and Cadence NCSim.
Currently only Transient Analysis of GoldenGate is available in cosimulation with Cadence NCSim.

Of course, Verilog-A(MS) models which include hidden states in analog block can't be treated in Envelope Analysis of Agilent ADSsim and GoldenGate.
Instead I can use special behavioral models called FDD in Envelope Analysis of Agilent ADSsim.

(1) Envelope Analysis(both shooting and HB) of Cadence is available in AMS simulation ?

The Verilog-A models which include hidden states are refused in Envelope Analysis of Cadence Spectre.

(2) If there are hidden states in analog block of Verilog-AMS models, how to treat these hidden states in Cadence Envelope Analysis of AMS ?

Self followup.

Spectre RF New Features in MMSIM 6.2
AMS and SpectreRF Envelope Analysis Co-Simulation
Spectre RF now supports co-simulation with AMS Designer for envelope analyses such as multi-carrier, autonomous, and FM modulation.

Is this for both shooting and HB ?

Yes, it supports both HB and Shooting. It's slightly misleading that it's mentioned in the MMSIM62 release notes, because the capability comes in the IUS stream - but the IUS stream based on MMSIM62 or later contains this, which means IUS611 or later, I think...
