Witryna29 wrz 2024 · The left shift term ( <<) in your expression behaves as you expect. It shifts all 8 bits to the left by 3 positions, dropping the 3 MSB's and adding 3 0 bits to the LSB's. This gives you 8'b0001_0000. However, the right shift term ( >>) does not behave as you expect. It will always return 8 0 bits: 8'b0000_0000.
