Technical Support

FlowCAD Support

Customers who purchased products from FlowCAD and have a valid maintenance contract have access to software updates and technical support. You can call our hotline and ask questions on how to operate the products and if you find a bug, you can report the bug as well to receive a software update. To explain the functionality of the tools our application engineers can make an individual web session with Fastviewer. Or we can share application notes and short video tutorials with you.

Log4j Update

Log4j Update
Log4j Update

Log4j is a framework to log application messages in Java. In many comercial software products this is used over years as a de-facto standard. Log4j is a leading application for logging frameworks in software development. In the last days a security gap was discovered. There are log4j files in the current release of the Cadence PCB Design Software for OrCAD and Allegro 17.2 and 17.4. If you scan your installation folder, you can see if your installed release contains these files.





These files are being used only by these applications:

  • data management in Cadence EDM
  • in OrCAD Capture when placing external parts: Function Place > Search Providers

Update for Version 17.2

ISR Hotfix 080 is now available at downloads.cadence.com. This is the recommended permanent fix for ALL 17.2 installations. This ISR removes all log4j-files. Zero-Day- and Denial-of-Service-Attacks are no longer possible.

NOTE: Apache has published log4j v2.17, but it was too late, the release Cadence ISR080 was already build. in a post process all critical log4j files were removed, so ISR080 has no more security gaps. But some virus scanner might still detect the log4j-version v2.16. In January a v2.17, based ISR081 will be released by Cadence which will bpass the scanners too. The release ISR080 will completely close the security gap and your IT will be safe. There is no reason to wait for ISR081, it just avoids false alarms.

Update for Version 17.4

The new 17.4 ISR025 was released on December 21st. It can be downloaded at support.cadence.com.

Recommended Literature

FlowCAD is often asked which books about PCB layout or signal integrity are recommended. We have listed here some books that our application engineers have read themselves and whose content we subjectively consider to be useful. This list is not exhaustive and FlowCAD has no commercial use for these book recommendations. If authors think that their books should be included here, please send us a preview copy. We will read and include it here if necessary.
