Data incoherency clock crossing
WebYou can use report_clock_interaction command which is generally used to report clock interactions and signals that cross clock domains to identify potential problems such a metastability or data loss or incoherency some visibility into the paths that cross clock domains is beneficial. This command requires an open synthesized or implemented design. http://www.gstitt.ece.ufl.edu/courses/spring11/eel4712/lectures/metastability/EEIOL_2007DEC24_EDA_TA_01.pdf

WebThe three main issues with clock domain crossing are: Metastability: a signal which between a logical high and logical low level. Data loss: a bit of information (literally: a bit) … WebThe CDC rules verify crossings between asynchronous clock domains. Crossings are verified against having combinational logic, convergence, or divergence. It is also checked, that a valid synchronizer is present on the crossing. For the asynchronous resets, de-assertion is verified to be synchronous with the proper clock.
