What is Verilog tmp_reg and Precision Errors about?
The tmp_reg register holds the product of slv_reg1 and slv_reg2, which is then assigned to slv_reg3. This is necessary because slv_reg3 may change values on the next clock cycle. Removing tmp_reg could result in the product not being correctly assigned to slv_reg3. If slv_reg1 and/or slv_reg2 contain fractional or decimal values, the multiplication will produce an incorrect whole number output due to a precision error. This type of error is commonly called a precision error. It could be corrected by declar
