Toggle Using AND/XOR Logic
Purpose: The purpose is to demonstrate neural toggling using AND/XOR Logic
The code used:
*itrig 0 1 dc ¼ 0 pwl(0,0,10us,5n,.2ms,5n,.21 ms,0)
vtrig1 22 0 dc ¼ 0 pwl(0,0,50 ms,0,50.01 ms,1V,50.2ms,
1V,50.21 ms,0)
x1 1 2 seg1
x2 2 3 segXOR
x3 3 4 seg1
x4 4 5 seg1
x5 5 6 seg1
X6 6 7 seg1
x10 7 1 buf
x11 22 1 bufv
x12 22 24 bufv
x13 7 24 buf1
x14 24 25 segAND
x15 25 26 buf
x16 26 2 seg1
The buffer-synapses used are given below. Buf1 is a simulation artifice that
serves to compensate the overly strong x10.
