Configuration & Testing
The Stratix II GX device instruction register length is 10 bits and the
USERCODE register length is 32 bits. Tables 3–2 and 3–3 show the boundary-
scan register length and device IDCODE information for Stratix II GX
devices.

SignalTap II
Embedded Logic
Analyzer
Stratix II GX devices feature the SignalTap II embedded logic analyzer,
which monitors design operation over a period of time through the IEEE
Std. 1149.1 (JTAG) circuitry. You can analyze internal logic at speed
without bringing internal signals to the I/O pins. This feature is
particularly important for advanced packages, such as FineLine BGA
packages, because it can be difficult to add a connection to a pin during
the debugging process after a board is designed and manufactured.
Configuration
The logic, circuitry, and interconnects in the Stratix II GX architecture are
configured with CMOS SRAM elements. Altera^® FPGAs are
reconfigurable and every device is tested with a high coverage
production test program so you do not have to perform fault testing and
can instead focus on simulation and design verification.
Stratix II GX devices are configured at system power-up with data stored
in an Altera configuration device or provided by an external controller
(for example, a MAX^® II device or microprocessor). You can configure
Stratix II GX devices using the fast passive parallel (FPP), active serial
