I gather these aren't for memory mapped IO ports? Does your program under test just have a collection of things like Voltage : Integer_8; -- etc that you want to examine/modify from a second program/task? It sounds like you essentially want to put those variables in a place in memory where they can be accessed from either testee or tester. Are the variables of interest sprinkled about, or are they in a few clumps? Can you put them in a shared passive partition and have another parition be the examiner/modifier? Or can you tell your linker to put those clumps, or at least the packages containing them, at set locations in sharable memory? Using a symbol table of course lets you leave the items of interest wherever the linker put them, but perhaps you can instead move the items to a more convenient spot - without significant change to the program under test.
