WebHello, We get max transition violations after RC extraction analysis. They don't show up during P&R optimizations. All of the violation nets are high buffer nets but not clocks. One is a reset and the others are not clock or reset. The … WebJul 28, 2024 · 586 Views. Without looking at your design, if these clock domains are asynchronous, you should use set_clock_groups to simply cut all paths between them. By using set_max [min]_delay, the tool will still analyze timing on paths that go between these clock domains and you see what's happening.
WebTo verify the set_clock_groups constraint, you can open_synthesized design and report timing between 2 clock domains: report_timing -group [get_clocks clk_125MHz] -group [get_clocks clk_out2_clk_wiz_300IN_1] -name test The requirement of the reported path should be infinite, it means the set_clock_groups constraint takes effect. WebThe Set Clock Latency (set_clock_latency) constraint allows you to specify additional delay (that is, latency) in a clock network. This delay value represents the external delay from …
WebMar 27, 2024 · set_max_transition sets the maximum transition time, a design rule constraint, on specified clocks, ports, or designs whereas set_input_transition sets … WebIf you want to run a tuning session with unlimited time per model, then set one of the tuning time limit parameters (either wall-clock tuning time limit in seconds …
Webmax_transition: This attribute is applied to each output of a cell. During optimization, Design Compiler tries to make the transition time of each net less than the value of the max_transition attribute. 2. set_max_transition: This command is used to change the maximum transition time restriction specified in a technology library.
