Abstract
The present application relates to a resistance simulation method for a power device, comprising: establishing an equivalent resistance model of a power device, wherein the connection relationship of N fingers is equivalent to N resistors Rconnected in parallel, input ends of adjacent resistors Rare connected by means of a resistor R, output ends of adjacent resistors Rare connected by means of a resistor R, and R=R*N+R+R, wherein Rand Rare respectively resistances of a source metal strip and a drain metal strip, Ris a metal resistor of a first intermediate layer connecting one source region to the source metal strip, Ris a metal resistor of a second intermediate layer connecting one drain region to the drain metal strip, and Ris the channel resistance of the power device; and calculating the resistance of the equivalent resistance model as the resistance of the power device.
