INTRODUCTION TO IMS METHOD FOR THE
THRESHOLD REALIZATION
Implied Minterm Structure (IMS) method
IMS method 2
IMS method 3
IMS method 4
IMS method• Write down the minterms
• These should be positive and ordered , ri>=N(1)/N(0) , this ratio in each column should be r1>=r2>=r3>=r4>=r5>=1
• Write it down in the IMS chart
• Select Nested F’s
• Realize each zone by Dertouzo’s method
• Connect with the help of OR gate(I/p +1,-1)
