mix analog and digital signals -凯发k8网页登录

combine analog circuit behaviors with digital models to create more detailed representations of electronic systems

in electronic systems that combine analog processing with logic gates, several parameters are essential to the overall behavior of the system. these parameters include the finite slew rate of circuit output signals, the propagation delay of signals, and the exact decision threshold of circuit inputs. add blocks to your model to include these effects in time domain simulations of the system.

blocks

generate or modify linear circuit
model amplitude, rise and fall times, and propagation delay of logic gates
threshold crossing detector at input to binary process
model operational amplifier with two or more poles
delay samples by controlled, continuously variable amount
convert signal from one sample time to another
convert scalar integer to binary logic vector and vice versa
generate clock signal with one or more phases
sample incoming signal at the edge of incoming clock

functions

convert signal from one sample time to another
converts transient analysis simulation results from synopsys to csv file or matlab table
