Hi Pranneth,
Once you have the DC butterfly curves for the two inverters, even in read or write mode, you can find the NM by summing (or substrating) the same increment ("h" on my code) in each inverter to determine the minimum square between the curves. It can be made until achieve the correct number of intersections that define the SNM as well. Next, my example for the write SNM:
if true
[Xint,Yint] = polyxpoly(vout1,vin1,vin2,vout2);
h = 1e-3;
SNMwSim = 0;
if (length(Xint)>1) %intersections number > 1
while (length(Xint)>1)
SNMwSim = SNMwSim - h;
[Xint,Yint] = polyxpoly(vout1,vin1-SNMwSim,vin2+SNMwSim,vout2);
plot(vout1,vin1-SNMwSim,vin2+SNMwSim,vout2)
%pause(0.2)
end
else % assuming that always we have at least 1 intersection
while (length(Xint)==1)
SNMwSim = SNMwSim + h;
[Xint,Yint] = polyxpoly(vout1,vin1-SNMwSim,vin2+SNMwSim,vout2);
plot(vout1,vin1-SNMwSim,vin2+SNMwSim,vout2)
%pause(0.2)
end
end
end
