The absolute path is required for configuring the Modelsim simulation Rom. MIF file.

When I used Modelsim to simulate Rom last night, all the output data was 000. This was never done before. Is Modelsim broken?
I tried a previous Rom test file and showed it to be normal. That's strange. Isn't it so unfamiliar if I haven't touched it for two months?

Then start to find the cause. the Last Post says that if the Rom has no output, it may be the IP Core configuration file, and the absolute path must be used for the initialization file. then I changed the configuration file's initialization to the absolute path. that's all.

However, I checked the previous tests. There is no absolute path. Alas ~~~ We can only say that Modelsim still needs to be enhanced!
