During the process of FPGA design, it is common to encounter warnings during compilation indicating that some latches have been generated. Generally, the design rules for FPGAs also advise against the generation of latches. So, what exactly is a latch? And how can we avoid the occurrence of latches in FPGA design?1 Comparison of Latches, … Read more
According to the Cadence user guide, the Multi-bit flip-flop (MBFF) flow provides power optimization benefits with minimal impact on timing. This flow is utilized as part of the pre-CTS optimization stage. The term multi-bit cell can be understood as merging multiple identical cells into a single cell. As shown in the figure below, the clock … Read more
1. What are Setup and Hold Times? Answer: Setup time refers to the time during which the data signal must remain stable before the clock edge, while hold time refers to the time during which the data signal must remain stable after the clock edge. If the setup and hold times are not satisfied, the … Read more
