Virtuoso ICADVM20.1 ISR17 and IC6.1.8 ISR17 Now Available

23 Mar 2021 • 4 minute read

The ICADVM20.1 ISR17 and IC6.1.8 ISR17 production releases are now available for download at Cadence Downloads. For information on supported platforms and other release compatibility information, see the README.txt file in the installation hierarchy.

We are no longer providing incremental software releases (ISRs) for the ICADVM18.1 release stream. ICADVM18.1 ISR13 was the final ICADVM18.1 ISR released. The recommended replacement release stream for ICADVM18.1 is ICADVM20.1.

Infrastructure Updates

In line with base releases and ISRs of other Cadence products, the ICADVM20.1 ISR17 and IC6.1.8 ISR17 releases now require FlexNet license server version v11.16.4.0 or higher. From these releases forward, you will no longer be able to run the software using older FlexNet versions. To upgrade your license server, you must download and install the latest Cadence Lic+Config_Utils release for Linux platforms (LCU04.30.000 and later). For more information, see the announcement on Cadence Downloads.
In the ICADVM20.1 base and IC6.1.8 ISR14 releases, X virtual framebuffer (Xvfb) replaced cdsXvnc as the default display server for Virtuoso running in non-graphics mode. Starting from ISR17, cdsXvnc is no longer shipped with the Virtuoso Custom IC design platform. You must now download Xvfb.rpm and install Xvfb in /usr/bin. After installation, this change will be transparent to the users. Before running simulations from the Virtuoso ADE product suite, ensure that Xvfb is installed on all computers where the netlisting jobs, such as ICRP or the netlisting process in LSCS, are running.

Here is a listing of the most important updates made in the current releases:

ICADVM20.1 ISR17 Only

Revamped Export Die Form (Virtuoso RF Solution)
Use the redesigned Export Die form for improved usability to match the evolving use model and to facilitate the inclusion of further options in the future.

Save and Load Settings for EM Simulators (Virtuoso RF Solution )
Use the Save and Load commands in the Simulation Settings form to save the simulation settings in a text file and load them later in the same or a different cellview.

Differential Ports for EMX Planar 3D Solver (Virtuoso RF Solution )
Create differential ports for models that use EMX Planar 3D Solver to run electromagnetic simulations by assigning a disabled port as a reference for another port.

Extract Connectivity Information from Package Layout (Virtuoso RF Solution )
Use the Save Connectivity form to extract connectivity information from package layouts. This information is saved to a text file, which can later be applied to other package schematics or layouts.

Use Assisted Move to Reposition Pins (Virtuoso Layout Suite EXL)
Use the Assisted Move Location column in the Pin Browser of the Pin Tool to move pins to predefined locations within the current design.

ICADVM20.1 and IC6.1.8 ISR17

Running the Pin Checker (Virtuoso Layout Suite XL)
Use the Layout vs schematic option of Pin Checker to compare the layout view with its corresponding schematic view to identify and report any additional pins present in either of these views.

Creating Pins from Labels (Virtuoso Layout Suite XL)
Use the Schematic Aware option in the Create Pin From Label form to create only those pins in the layout that have corresponding pins in the schematic view.
