Does module shift_right1 perform a logical right shift on a 16-bit quantity?
Module shift_right1 is supposed to perform a logical right shift on a 16-bit quantity. Your solution should assign shifted one bit at a time, as does the existing code. (In other words, don’t just use the right shift operator.) The testbench output might provide clues to what the problem is.
Should arithmetic shift operators be used with Verilog signed types?
In contrast, the arithmetic shift operators preserve the sign of the shifted signal. As a result of this, they should only be used with the verilog signed types. The code snippet below shows how we use the shift operators in practise.
What is the difference between logical shift and arithmetic shift?
arithmetic right shift ( >>>) - shift right specified number of bits, fill with value of sign bit if expression is signed, otherwise fill with zero, arithmetic left shift ( <<<) - shift left specified number of bits, fill with zero. On the other hand, logical shift ( <<, >>) always fill the vacated bit positions with zeroes.
What is the second argument in logical shift operator?
The second argument is the number of bits we want to shift. When we use the logical shift operators, all the blank positions are filled with 0b after the signal has been shifted by the required number of bits.
