Design Implementation
Once the datapath block diagram and ASM chart is done, the ‘design’ work is done. What is left is implementation.
Decide what parts of the datapath will be implemented in VHDL, what parts using LPMs
- The FSM control will certainly be done in VHDL
- Misc registers can be easily included in the VHDL FSM code as well instead of using separate datapath components.
Do the schematic of the datapath FIRST!
- Sometime just hooking up the datapath elements will expose a flaw in your reasoning.
