i used a DMux8WAy, 8 Registers and 1 Mux8Way16 to implement the RAM8 chip. The comparison failed at beginning and reminded me that:"line 19, in(1) and in(16) have different bus widths", but all in=in in the Register, why does they have different widths?
should i paste the code? it seems inappropriate to paste all the code here.
the register is like this :
Register(in=in, load=loada, out=routa);
Thanks for your help.
