|
|
|
Like in Verilog, VERA supports left and right shift operators as shown below. |

Description
|
|
<<
|
left shift
|
|
>>
|
right shift
|
|
| |
|
|
|
|
- The left operand is shifted by the number of bit positions given by the right operand.
- The vacated bit positions are filled with zeroes.

Example : Shift Operators
|
| |
|
|
|
|
1 program shift {
2 // Left Shift
3 printf (" 4'b1001 << 1 = %b\n", (4'b1001 << 1));
4 printf (" 4'b10x1 << 1 = %b\n", (4'b10x1 << 1));
5 printf (" 4'b10z1 << 1 = %b\n", (4'b10z1 << 1));
6 // Right Shift
7 printf (" 4'b1001 >> 1 = %b\n", (4'b1001 >> 1));
8 printf (" 4'b10x1 >> 1 = %b\n", (4'b10x1 >> 1));
9 printf (" 4'b10z1 >> 1 = %b\n", (4'b10z1 >> 1));
10 }

4'b10z1 << 1 = 0z10
4'b1001 >> 1 = 0100
4'b10x1 >> 1 = 010x
4'b10z1 >> 1 = 010z
