Hi jimwu88,
Thanks for your reply. Yes I agree the question is kind of vague having gone through it second time now. What I was trying to ask can be summarized as follows :-
Let's say I have an IP for which data has to be written into it's configuration registers to control it's functioning. So the only approach I knew was to give it some kind of a software interface/drivers by wrapping the IP around a bus wrapper (let's say in case of xilinx- exporting the design as PCORE or writing a PLB/AXI wrapper to connect it to Microblaze).
According to what I read - "Instead of writing drivers, shell scripting can be used to control the IP". So I was not clear how exactly script was of help here. That was my question (whether the script recompiles and generates new bitstream or else it acts as a substitute for a Processor to write into the config registers) ?
