Design Challenges and Implementation DecisionsFor The Past Week
Problems/Questions • Small Problems with Control Logic in Schematic • Can we reduce more transistors with better logic ? • Any way to move the SRAM from the middle of our chip?
For Next Week • Perfect our Control Logic in the Schematic • Continue to reduce and optimize gates • Start Layout !
