If your Simulink ® model contains multiple sample rates or uses speed and area optimizations that insert … WebMulticycle Path Analysis. 1.1.5. Multicycle Path Analysis. Multicycle paths are data paths that require an exception to the default setup or hold relationship, for proper analysis. For example, a register that requires data capture on every second or third rising clock edge (multicycle exception), rather than requiring capture on every clock ...

In your case, the lack of clock-enable on capture_com_rx_packet_counter would make it "unsafe". It should be possible to force the synthesis tool to use a flip-flop primitive with a clock-en, which would be the first step to …

If we compare Figure 4.27 to the datapath for the single-cycle version in Figure 4.11 on page 250, we can see the following differences: A single memory unit is used for both instructions and data.
WebHold multicycles (-hold) are computed relative to setup multicycles (-setup). The value of the hold multicycle represents the number clock edges away from the default hold multicycle. The default hold multicycle value is 0. The -from and -to values are collections of clocks, registers, ports, pins, or cells in the design.
