I STRONGLY advise you to use 'nominal mapping' (e.g., clk=>clk)which might take a little more effort but will avoid errors like you have (You've mapped clk to D and vice versa in your code when I THINK what you want is to map Q(z-1) to D). First of all, you don't need to 'discard' the MSB when you shift D7 to Q7, the old Q7 just 'disappears'.Д«ut a bigger problem for you is that you've used 'positional mapping', which is a sure-fire way to shoot yourself in the foot.

Im having a bit of trouble with the code to discard the most significant bit.ДЄny help will be greatly appreciated thanks Here is my code so far. The most significant data bit is discarded once each new bit is accepted. Serial data is accepted at the shift register input on a rising clock edge and is placed in the least significant bit вЂ“ the other 7 bits of existing data shift to left. In my programme i have to Design a Serial In, Parallel Out, (SIPO) sift register with a Clock and Data input (both single lines and an 8-bit parallel output Q. VHDL Code Following is the VHDL code for an 8-bit shift-left register with a positive-edge clock, asynchronous clear, serial in, and serial out. The following code models a four-bit parallel in shift left register with load and shift enable signal. Following is the VHDL code for an 8-bit shift-left/shift-right register with a positive-edge clock, serial in, and serial out.Д«it serial shift in and shift out register without enable signal.
