他是说data_read_local_n产生了latch。警告提示是这样的:“Warning (10240): Verilog HDL Always Construct warning at SDA_Generate.v(203): inferring latch(es) for variable "data_read_local_n", which holds its previous value in one or more paths through the always construct.”
问题可能不在这里,在你没贴出来的地方。
那您知道除了:if没写完整,case没写全,变量没有在所有情况下都给予了赋值,这些之外还有哪些情况会产生latch呀?
