and the same for input, data in will be divided to 4 parts saved in 4 consecutive memory addresses starting at "address". please i need help in how to write this in verilog, the dr advised searching the internet but i didn't find what i was looking for though there's alot of cod...
Warning: Inferred dual-clock RAM node "Memory~0" from synchronous design logic. The read-during-write behavior of a dual-clock RAM is undefined and may not match the behavior of the original design. Will this be where the problem comes from? How could I edit ...

View Code 总结:这里没有对代码和时序图的具体分析。关于实现的过程主要要有一个大概的输入输出框图。 单口的RAM:记住下面的框图,和接口的走向,剩下的了解逻辑就可以写出来了。注意:DATA的数据类型。 伪双口RAM: 双口RAM: 实际应用注意: (1)无论是简单双口RAM还是真双口RAM,在没有读操作的情况下,应将读使...

26、how you can read and write files in a Verilog model usinga set of user functions, based on the C stdio package. With these functionsyou can perform file input and output directly in Verilog models withouthaving to learn C or the PLI. This code works with VCS, MTI, Verilog-XL 27、...
