函数比较多,常用的有$clog2,即在已知memory size计算address位宽时使用。 •波形记录。可以根据喜好 ,dump生成VCD或fsdb类型的波形文件。一个简单fsdb dump示例:initial begin $fsdbDumpfile(test.fsdb); $fsdbDumpvars(“+all”);end。如果工程较大的话,会用到不同的波形记录任务,可以只dump特定层次,特定模块...

initial blocks where reg values are established instead of using a “reset” signal. ASIC synthesis tools don't support such a statement. The reason is that an FPGA's initial state is something that is downloaded into the memory tables of the FPGA. An ASIC is an actual hardware ...
