When compiling lower levels it may be necessary to inhibit IO buffer insertion with a compile option. It is possible to write VHDL code where the logic of a design unit depends upon another design unit. For example if generics, or ports of an unconstrained array type, or signals declared ...

In this example we see how we can use a generic to adjust the size of aport in VHDL. Rather than using a fixed number to declare the port width, we substitute the generic value into the declaration. This is one of the most common use cases for generics in VHDL. We can use this app...

Rather than having your generic values hard-coded by storing them in a package, use the Quartus and Modelsim Tcl scripting capabilities to set generics inside a loop. For example, I have a board with four identical FPGAs. The FPGAs get programmed with a device ID (0 to 3) and that ...
