Allegro 17.4 Analysis Workflow

EnottonE

Question about Allegro 17.4 Analysis Workflow. Before a certain hotfix (it seems to be up to 11 or 14), the diff. pair impedance analysis worked without problems, now when starting the analysis, it is required that the sigrity 2021.1 package with the latest hotfix be installed (probably some libraries are needed). Do I need to install Sigrity, even though there is no license for it (only Allegro license was purchased) in order for the analysis to work? Maybe allegro will pick up the necessary components? Or is the Analysis Workflow functionality now completely unavailable?

  • The required components are now distributed and maintained through the Sigrity 2021 installation for PCB Editor 17.4, as they were previously by Sigrity 2019 installation for 17.4. Previously components were potentially duplicated in both product installations. The PCB Editor license provides the rights to use the Sigrity components in the Analysis Workflows.

    So the out of the box experience is basically "DOA" because of the dependency on sigrity in particular for new deployments ?

    This  makes no sense because there is an assumption that a user would want Sigrity. to begin with.

    Not shooting the messenger here OldMouldy & thanks for the info on this.

    Believe Cadence needs to re-think this and fix their "Installers" to do a go / No go on installing components. As is all this change is doing is driving "Tech Support" in a negative way, eh not good.
