Incremental synthesis is a production feature since the 2019.1 release. It addresses the need for fast iterations during the synthesis phase, significantly reducing compile time while also ensuring predictable results, with no cost of QoR loss.
Compile time is always a key concern in design cycles. In this blog, we will cover the techniques for design compile time reduction, following the flow of design entry, synthesis, and implementation. This blog will be updated regularly, with more subtopics links added as they completed.
Clock gating in RTL is a common way of reducing power in ASICs, however it not translate well to FPGAs. Because of that, FPGA synthesis tools will have a feature that can convert gated clocks. This article will speak to how Vivado Synthesis converts gated clocks and how to control the feature.
