Wrong decoder behaviour in flat simulation #564

Closed LuminousXLB closed 1 year ago

LuminousXLB commented 1 year ago

As in the figure below, the expected output is 7 but 1 is given.

Here's the script:

var val = I0 + 2 * I1 + 4 * I2
O0 = EN and val == 0
O1 = EN and val == 1
O2 = EN and val == 2
O3 = EN and val == 3
O4 = EN and val == 4
O5 = EN and val == 5
O6 = EN and val == 6
O7 = EN and val == 7

I guess the first line shall be changed to var val = 1 * I0 + 2 * I1 + 4 * I2 to cast it to number instead of bool.

@LuminousXLB Thank you for reporting this. You are exactly right with your guess about the script. We will deliver the fix with our next release soon.

BTW, the same bug is also in the scripts for 2-4 DEC and 4-16 DEC.
