Hello. I have to do assignment with D trigger, but I'm total noob with it, and now I stuck. So I think, maybie enyone can help me to do it?! The equation is not_X1 Qt+X1((X2 XOR not_X4)*X3) (with not_ i mean overbar) synchrony signals is not_C1 and C2.I already have done this board:
x2 x3 x4 D Qt not_Qt
0 0 0 0 0 1
0 0 1 0 0 1
0 1 0 1 1 0
0 1 1 0 0 1
1 0 0 0 0 1
1 0 1 0 0 1
1 1 0 0 0 1
1 1 1 1 1 0
And now I have to make a circuity using ispLEVER Classic.. And here I am stuck. I tried to make one : . But when I test it (i use test:
MODULE schema04;
"inputs
X1, X2, X3, X4 pin;
"output
Qt pin istype 'com';
Test_vectors ([X1,X2,X3,X4]->Qt)
[0,0,0,0]->0;
[0,0,0,1]->0;
[0,0,1,0]->1;
[0,0,1,1]->0;
[0,1,0,0]->0;
[0,1,0,1]->0;
[0,1,1,0]->0;
[0,1,1,1]->1;
[1,0,0,0]->0;
[1,0,0,1]->0;
[1,0,1,0]->0;
[1,0,1,1]->0;
[1,1,0,0]->0;
[1,1,0,1]->0;
[1,1,1,0]->0;
[1,1,1,1]->0;
end; )
