Recommendations
The following recommendations are for all automotive appli-
cations.
1. Use strict synchronous design (only one clocking event)
2. Include JTAG stakes on the PCB. JTAG stakes can be

regulator needs to provide at least three times the peak
current while powering up a CPLD in order to guarantee
the CPLD can configure successfully.
