Signal Integrity – CADSTAR SI Verify

As more designs incorporate high-speed technologies and involve integrated circuits (ICs) with rapidly increasing fast edge rates, the need for signal integrity analysis has become a vital part of the product development cycle. Signal quality is an important factor in the performance of the overall product, so the need to analyze crosstalk effects, over/undershoot, propagation delays and the evaluation of different termination schemes can help identify problems early in the design process, and avoid unnecessary design failures and costly iterations.

High-speed interfaces such as DDRx and PCI Express demand complex timing requirements that cannot be resolved by applying traditional rules of thumb to secure effective signal quality. CADSTAR SI Verify offers a complete concurrent and post-layout signal integrity solution that enables engineers, layout designers and specialists within a development team to collaborate, organize, constrain, and verify their design in a seamless process. This helps them work more effectively, minimize costs, and improve overall time to market.

Top features and benefits
