Testing for MAX II Devices
The MAX II JTAG block feature allows you to access the JTAG TAP and state signals
when either the USER0 or USER1 instruction is issued to the JTAG TAP. The USER0
and USER1 instructions bring the JTAG boundary-scan chain (TDI) through the user
logic instead of the MAX II device’s boundary-scan cells. Each USER instruction
allows for one unique user-defined JTAG chain into the logic array.
Parallel Flash Loader
The JTAG block ability to interface JTAG to non-JTAG devices is ideal for general-
purpose flash memory devices (such as Intel- or Fujitsu-based devices) that require
programming during in-circuit test. The flash memory devices can be used for FPGA
configuration or be part of system memory. In many cases, the MAX II device is
already connected to these devices as the configuration control logic between the
FPGA and the flash device. Unlike ISP-capable CPLD devices, bulk flash devices do
not have JTAG TAP pins or connections. For small flash devices, it is common to use
the serial JTAG scan chain of a connected device to program the non-JTAG flash
device. This is slow and inefficient in most cases and impractical for large parallel
flash devices. Using the MAX II device’s JTAG block as a parallel flash loader, with
the Quartus II software, to program and verify flash contents provides a fast and cost-
effective means of in-circuit programming during test.
