I want to use the output of a R-C integrator as a delayed input to CPLD
(inside there is a XOR gate and counter logic). It worked OK when I use
discrete XOR IC 4070. But for same R-C values it doesn't works with
CPLD.
Is is due to the fact that analog input (sawtooth from integrator) has
given to CPLD?
Is comparator after integrator is one of the solution?
Suggest other methods for creating delays inside CPLD. That will
elliminate need of integrator. Here delay required is 1.1us.
