XAPP440 - Xilinx CPLD的上电性能

Applying power to a standard logic chip, SRAM, or EPROM, usually results in output pinstracking the applied voltage as it rises. Programmable logic attempts to emulate that behavior,but physics forbids perfect emulation, due to the device programmability. It requires care tospecify the pin behavio ...
