Simulations using ADE (G)XL

Setups for proper usage of ADE XL for NCSU CDK

• Edit .cdsenv in the project library, add the following lines

; To run adexl properly for NCSU PDK
adexl.icrpStartup  binaryName string "virtuoso -nocdsinit"

Simulations using ADE (G)XL

• Create a new ADE (G)XL by going to Launch--> ADE XL in your schematic windows. You will have the choice to create a new view or open and existing view. Here we will just use the default as shown below.

• In the
• Create a Test using schematic view (Schematic view can be only used for schematic simulation. It is highly recommended to create a test using config view, which can be conveniently used for both schematic and postlayout simulation).

Parameter sweeping

• Option 1
  • Double click the parameter value
  • Click the button on the right of the value
  • Run simulation

• Option 2
  • Setup the parameter sweep in ADE L
  • Save the setup to an .il file
  • Load the saved .il file into ADE (G)XL parameter setup
  • Run simulation

Postlayout simulation

• Create a test in ADE (G)XL using schematicview
• Setup the simulation configurations (or, you can setup the simulation configurations for schematic view in ADE L and save the state. Load the saved state).
• Setup the extract view: parasitics>setup>choose the cell to setup its schematic, estimated, an extracted view
• Run the simulation
  • No parasitic: schematic simulation
  • Extracted: postlayout simulation
