Multi-ICE Test Interface
This section describes the LSI Logic requirements for the Multi-ICE test
interface. LSI Logic recommends that all test signals be routed to a
header on the board.
The Multi-ICE test interface header is a 20-pin header for Multi-ICE
debugging through the ICE JTAG port. This header is essential for
debugging both the firmware and the design functionality and must be
included in board designs. The connector is a 20-pin header that mates
with the IDC sockets mounted on a ribbon cable.
Table 2.6 details the
pinout of the 20 pin header.
