The SPB16.3 release of Design Entry HDL (DEHDL) provides an easier method for setting up the PCB SI model library path, and brings more consistency to the Front-to-Back (F2B) and Back-to-Front (B2F) flows.
Signal Integrity (SI) models are essential for running an SI simulation. PCB SI is an integrated solution with DEHDL and Allegro PCB Editor. When a design is moved from one engineer’s system to another engineer’s system, you need to ensure that the SI model PATH is correctly defined and available. Most of the time it is manually corrected. There is lot of confusion on how to effectively set the Device Modeling Language (DML) search paths and the preferences which configure simulation runs and retain data from one run to another, even when design is moved from one system to another. By setting up the SI Model path as a .cpm file directive you can set the models at the site level and make the design more portable.Read on for more details …
Pre SPB16.3 behavior
Behavior in SPB16.3
Changes in the SI Model Setup UI
Only Library Paths can be added / deleted. The option to add / delete the dml and ndx file is removed.New User interface for managing individual libraries (LM symbol in library setup):
The new Library Management interface is used for the:
Migration from previous releases to SPB16.3
You need to run one of the following to move the SI model path defined in the previous release to the .cpm file directive.In DEHDL automatic uprev on launch of:
In ASA the design paths are read from the signoise.run folder and added to the .cpm file
Diff Pair Renaming
With the SP16.3 release you can now change or modify the Diff Pair Name. For Model Defined and Library Defined Differential Pairs the Differential Pairs are automatically created on launching the Constraint Manager with a Tool Assigned name.
To rename a Diff Pair Name in Constraint Manager, select Diff Pair and Right Click Rename:To revert back to a Tool Generated name, use the Use Default button.
New Properties effecting the CM flow:
Looking forward to your feeback on using these new features.
