Hold time fixing

NettetHold Time Constraint. The register R2 in Figure 3.38 (a) also has a hold time constraint. Its input, D 2, must not change until some time, thold, after the rising edge of the clock. According to Figure 3.40, D 2 might change as soon as tccq + tcd after the rising edge of the clock. Hence, we find. Nettet22. jun. 2024 · Hold time fixing ensures correct data synchronization, which is essential and serves as the final step of timing closure for IC design. Conventionally, buffer insertion is adopted to fix hold time violations; buffers, however, induce routing difficulty, increase area utilization, and contribute leakage power. Therefore, in this paper, we propose to …
