Product Term Allocation 3 available here 2 p-terms required here 5 available here 5 native p-terms 5 available here TIB_arch. B 1 Total = 18 requires 2 X tpta delay added to t. PD

Industry’s Best Pin-Locking w Product Term Allocator allows any product term to be borrowed by any macrocell in the same function block w Product Term Allocator allows for timing to be held for small to medium logic changes w Footprint compatibility allows for easy migration to larger or smaller devices using the same device package TIB_arch. B 1

Why Pin-Locking is Necessary w The major advantages of In System Programming can only be realized with field-upgrades w It does not make sense to do field upgrades if the board needs to be reworked for minor logic changes w It does not make sense to do field upgrades if timing cannot be met TIB_arch. B 1

Pin Locking vs Pin Preassignment w The software should be allowed to make first pass pin assignments w Pre-assigning pins can lead to timing and density underutilization TIB_arch. B 1

ISP w Original XC 9500 JTAG and ISP instructions: — Program Erase Blankcheck — ID Code Usercode — Intest Extest Verify Hi-Z Bypass w New instruction: — CLAMP — permits pin by pin definition of logic level during bypass w Added S/W support with XACT M 1. 5 TIB_arch. B 1

Bus Hold Logic w A weak latch holds last state on I/O w RBH= 50 k. Ohms TIB_arch. B 1

Bus Hold Logic w Two modes of operation — User mode: Holds last state — ISP or blank device: pull-up resistor w Better than just a pull-up resistor — eliminates slow changing of bus signals during hi-z — reduced system power during TIB_arch. B 1
