FUNCTIONAL DESCRIPTION
CORE: Core module interconnects all the sub-modules in the ASRAM Controller IP. Ports of core module are the top level ports for the ASRAM Controller IP.
FSM: ASRAM Controller IP FSM manages control signals, to control read/write flow. Ensures ASRAM timing requirements like access time, setup time, hold time, and write pulse width. Also controls data direction by switching the data bus between input and output during reads and writes.
CSR: CSR module has all the registers. The contents of the registers are decoded and assigned to its respective output ports based on its functionality.
