HBM3 Architectural Specific Checks and Timing Closure

A System on a Chip (SoC) is a condensed integrated circuit combining all the system’s crucial components onto a single chip. A physical interface with the (High Bandwith Memory 3)HBM3 architecture will be designed to integrate the SoC and the memory module. Due to the usage of the synchronous clock across the IP blocks, the essence and the criticality of meeting the timing of any block will be high. The architectural-specific checks like clock latency, clock skew, and data skew are fixed for particular architectures like HBM3 to maintain the synchronization between the data signal and the clock signal. the architectural-specific checks given by the design team to meet the timing closure of any block related to the customer requirement. The timing closure during the tape-out stage of any design using generic timing checks such as the Setup and Hold with zero Violations will be crucial. The optimization ideas like the Vt-Swap, inserting buffer to the worst slack path, and increasing the driving strength of the buffers to fix the specific checks to meet the timing closure. Finally, the HBM3 physical interface’s timing should be clean before the tape-out.
