CPLD Powerup RESET

Hello,

I need to RESET the CPLD at the powerup of the system. My CPLD (
ATF1508AS-7QC160) has 3.3volts power supply and input voltage of 3.3
volts.
Would anyone recommend powerup RESET chip. I am trying to RESET the
state machines. Should I will be looking for rising edge of the RESET
signal or when it stablizes itself and stay high like 3.3 volts.

Thanks
Regards
John
 
You can try Maxim or ST. I've used the following in the recent past:
STM811TW16F (ST Electronics)
