What’s New in XCELIUM 25.03
Learn about the new features and enhancements available to you in this Xcelium release.
Upgrade to Cadence 2024 Platform Support
Starting with this release, Xcelium has upgraded to the Cadence 2024 Platform Support matrix. With this upgrade, the following changes now apply to Xcelium:
Build Platform Changes: RHEL 8.4 is now the default build platform for Xcelium. The following platforms are now EOL:
– CentOS 7
– RHEL 8.3 and previous versions
– SLES15 SP2 and previous versions
GCC Version Changes: For x86_64, GCC 12.3 is now the default compiler and GCC 9.3 is the secondary compiler. You can switch the GCC version by specifying -gcc_vers<version_number> on the command line.
Enhancement to Xcelium Extended Help Messages
Starting with the 24.10-a release, Xcelium now includes a Cadence Online Support (COS) link at the end of the extended help messages generated by the xmhelp tool. This link allows users to access more information specific to an error mnemonic. For example:
To disable this enhancement and skip the generation of the COS link, use: $ setenv CDNS_XLM_HELP_SEARCH_GENURL_SCRIPT none
– To generate a customer-specific link in case the customer has their own internal searchable online database for Xcelium errors, use: $ setenv CDNS_XLM_HELP_SEARCH_GENURL_SCRIPT <path to a script to generate customer-specific URL>
– To know more about customizing this feature, use: $ xmhelp xrun XLMHELPURL
New README Format
To improve accessibility, the Xcelium Release Information README collates the following content that was previously distributed using separate manuals: hardware and software requirements, installation and licensing information, new features and enhancements, and known problems. The separate manuals listed below are deprecated with the release of the new README:
– Xcelium Installation and Licensing Information
– What’s New in Xcelium
– Xcelium Known Problems and Solutions
New Documentation Tool
Xcelium includes a new cloud-based documentation tool. The Cadence Doc Assistant is a web-based application that lets you access the latest documentation for all the Cadence products installed on your machine or available online.
The Doc Assistant has the following advantages over Cadence Help:
– It has short, up-to-date, and relevant content organized by document types.
– It has two modes for viewing documentation:
. The default online mode shows the latest documentation from a cloud server.
. The offline mode shows the documentation from your installation hierarchy.
– It lets you browse content based on product features and sub-features.
– It retrieves search results from multiple Cadence resources at the same time, such as product and support documentation.
Launching Doc Assistant
To launch Doc Assistant from the product installation hierarchy, <xcelium_install>/tools.lnx86/bin, specify the following:./cda &

Cadence Xcelium Logic Simulator, a state-of-the-art Electronic Design Automation (EDA) tool used by engineers worldwide to verify complex System-on-Chip (SoC), IP, and digital logic designs before they ever hit silicon. Simply put, Xcelium is a high-performance, scalable simulator that lets engineers exhaustively test and debug hardware designs early in the development cycle, dramatically reducing time-to-market and design risk. It serves as a core verification engine in modern semiconductor verification flows taking system descriptions written in hardware description languages (HDLs) such as SystemVerilog, Verilog, VHDL, SystemC, and UVM-based testbenches and simulating their behavior in a controlled environment. Through simulation, engineers uncover logic errors, functional mismatches, timing issues, and other bugs long before tape-out, thereby saving substantial development cost and effort.
Are long DFT simulations posing a big challenge to meet your tight project schedules? We have a solution to accelerate the long running DFT tests. Watch this video to know how easy it is to set-up Xcelium Multi-Core to get up to 5X acceleration for a variety of DFT use cases ranging from serial and parallel ATPG to MBIST and LBIST
