"WebA typical memory model supplied by vendor contains lots of constructs to check setup, hold timing and protocol violations. One may not need execution of these checks once memory controller is stable. Often vendor provides a switch to disable these checks in run time. Use these switches to effectively speed up the memory simulation. " - Timing checks

WebIn simplest form a clock gating can be achieved by using an AND gate as shown in picture below. Figure 1: AND gate-based clock gating. The clock enable signal, generated by a combinatorial logic, controls when to provide the clock to the downstream logic (FF in the above figure). When enable is 1, the clock will be provided to FF and when ... WebThe setup and hold timing checks are needed to check the proper propagation of data through the sequential circuits. These timing checks are used to verify the data input (D) is unambiguous at the active edge of the clock so the proper data is latched at the active edge. These timing checks verify the data input is stable before and after the ...
