I want to pipeline a design. There are a possible four pipeline stages, and I want to be able to control the number of pipeline stages compiled using a config file.
In the config file I want to have the following
so that I can use
in my code to add the respective registers. I would like any combination of pipe line stages to be used or not used.
My question is, to control my pipeline, I want an array that will be used for clock enables. If all pipeline stages were defined, this would be a 4 bit array representing {PL1, PL2, PL3, PL4}. However, if say, only 2 pipeline stages were defined, PL2 and PL4, I would like a 2 bit array representing {PL2, PL4}.
Is there a neat way of creating this array?
