Post-Layout Verification of Parallel Link Projects

Verify the layout design of your system against design guidelines or specification rules

Post-layout verification allows you to verify the performance of your actual routed system against the design guidelines or specification rules. You can edit the vias and stackups and control the padstack models. You can also verify your design using PCB models. You can create topologies from extracted PCB data for pre-layout analysis.

Note

You need a RF PCB Toolbox™ license for the post-layout workflow.

Featured Examples

Post-Layout of DDRx Interface with CPU and DIMMs

Demonstrates the use of Parallel Link Designer in the Signal Integrity Toolbox™ in MATLAB® to set up a post-layout analysis of a DDRx interface on a Main Board having a CPU connected to two DIMM slots to verify that waveform quality and timing margins are met by the PCB database. Many of the steps illustrated in this example are also applicable to Serial Link Designer for post-layout analysis of SERDES links.
