There is a block in the SOC which has AHB reset and that block has a software reset also. The SOC has also a power on reset definitely. This block is one of the blocks of the SOC. How will the resets be provided to this block ? Will there be need to provide all the three resets, power on reset, AHB reset and software reset to be provided to this block? Which reset among these three resets should be de-asserted first and what should be the de-assertion sequence of these three resets to this block? Can we do AND or OR with these three resets together to generate a single reset for this block but in that case glitch may come. Please suggest.
