[myhdl-list] Generating 160 bit signal

[Edward V. <dev...@sb...>]

Hello All,
Trying to take 16 values from an image to generate 160 bit signal

lft_s_i.next = ((r[row+31][col] << W0*15) | (r[row+29][col] << W0*14) | 
(r[row+27][col] << W0*13) | (r[row+25][col] << W0*12) | 
(r[row+23][col] << W0*11) | (r[row+21][col] << W0*10) | 
(r[row+19][col] << W0*9) | (r[row+17][col] << W0*8) | 
(r[row+15][col] << W0*7) | (r[row+13][col] << W0*6) | 
(r[row+11][col] << W0*5) | (r[row+9][col] << W0*4) | 
(r[row+7][col] << W0*3) | (r[row+5][col] << W0*2) | 
(r[row+3][col] << W0*1) | (r[row-1][col] ))

Also works most of time with + instead | 

Most of the time it works 
working okay generates a signal of 160

This causes the error the signal needs 157 more bits

 All help is appreciated.
