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 ADE (G)XL
  • 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
