Iopath in sdf
WebAn SDF construct can have multiple matches, in which case each matching specify statement is updated with the SDF timing value. SDF constructs are matched to Verilog constructs as follows: IOPATH is matched to specify path delays or primitives: SDF. Verilog. (IOPATH (posedge clk) q (3) (4)) (posedge clk => q) = 0; (IOPATH a y (3) (4)) buf u1 (y ... WebSDF (Standard Delay Format),标准延时格式文件,常用延迟反标注。该文件包含了仿真用到的所有 IOPATH,INTERCONNECT、TIMING CHECK 等延迟时间和时序约束的参数 …
