Sdf gate level simulation

WebbThe most difficult part in gate level simulation (GLS) is 'X' propagation debug. 'X' propagation in GLS is mostly caused by 'X' pessimism, so it is practical to suppress them and focus on the main purpose of GLS. This use case shows how to suppress 'X' propagations in GLS while retain the capability to catch 'X' optimism issue. Webb11 mars 2024 · In this paper, we present GATSPI, a novel GPU accelerated logic gate simulator that enables ultra-fast power estimation for industry sized ASIC designs with millions of gates. GATSPI is written in PyTorch with custom CUDA kernels for ease of coding and maintainability. It achieves simulation kernel speedup of up to 1668X on a …

Webb27 nov. 2011 · Gate Level Simulations by anupam I have been doing timing gate level simulations recently. The purpose of the activity was to generate vcd snapshots to capture maximum activity on the design in order to calculate the IR drop of the design. Some of the open points are/were: 1) What is IR drop calculation? Why is it done? Webb4 aug. 2024 · Next I will talk about , what strategy should be adopted for Gate Level Verification. Lets divide the whole strategy into “ Five ” Steps. STEP 1 : GLS Test Plan. We run thousands of testcase in RTL simulation, but when it comes to GLS, due to long simulation time, we need to be really careful of what tests are being run.
