The 5.4 ns max propagation delay is the time from any input pin through the logic array to any output pin.
In-system programmable — no socket needed
The EPM570GT144C5N is in-system programmable via JTAG. No separate programmer socket is required on the board — just a 4-pin header (TMS, TCK, TDI, TDO) plus VCC and GND. The MAX II family supports both SRAM-based configuration and non-volatile storage, so the design holds its logic on power-up without an external configuration device. Programming is done through Altera's Quartus II software with a USB-Blaster or compatible JTAG cable.
