6.5.9. Register-to-Register Timing Optimization Techniques

The next stage of design optimization seeks to improve register-to-register (fMAX) timing. The following sections provide available options if the design does not meet timing requirements after compilation.

Coding style affects the performance of a design to a greater extent than other changes in settings. Always evaluate the code and make sure to use synchronous design practices.

Note: In the context of the Timing Analyzer, register-to-register timing optimization is the same as maximizing the slack on the clock domains in a design. The techniques in this section can improve the slack on different timing paths in the design.

Before performing design optimizations, understand the structure of the design as well as the effects of techniques in different types of logic. Techniques that do not benefit the logic structure can decrease performance.
