The operators are defined as follows, where L is the left operand and R the right operand: L sll R : Shift L logically left (R≥0) respective right (R<0) by R index positions. To fix this error, right click on the module "d_and_mux" and select "add Source" and locate the VHDL code, "Mux4_to_1.vhd" that we created at step 2 above. Do the same thing for "d_flip_flop". Save the module and now the error should go away as shown below. 5. Universal Shift Register VHDL code.
