3200DX Field Programmable Gate Arrays – The System Logic Integrator Family
Clock Networks
Two low-skew, high fanout clock distribution networks are
provided in each 3200DX device. These networks are
referred to as CLK0 and CLK1. Each network has a clock
module (CLKMOD) that selects the source of the clock
signal and may be driven as follows:
1.
Externally from the CLKA pad
2.
Externally from the CLKB pad
3.
Internally from the CLKINA input
4.
Internally from the CLKINB input
The clock modules are located in the top row of I/O modules.
Clock drivers and a dedicated horizontal clock track are
located in each horizontal routing channel.
The user controls the clock module by selecting one of two
clock macros from the macro library. The macro CLKBUF is
used to connect one of the two external clock pins to a clock
network, and the macro CLKINT is used to connect an
internally generated clock signal to a clock network. Since
both clock networks are identical, the user does not care
whether CLK0 or CLK1 is being used. The clock input pads
may also be used as normal I/Os, bypassing the clock
networks (see Figure 7).
The 3200DX devices which contain SRAM modules (all
except A3265DX and A32140DX) have four additional
register control resources, called Quadrant Clock Networks
(Figure 8). Each quadrant clock provides a local, high-fanout
resource to the contiguous logic modules within its quadrant
of the device. Quadrant clock signals can originate from
specific I/O pins or from the internal array and can be used as
a secondary register clock, register clear, or output enable.
Test Circuitry
The 3200DX provides two modes of device and/or
board-level testing; JTAG 1149.1 Boundary Scan Testing
and Actel’s Actionprobe test facility. Once a 3200DX
device has been programmed, the Actionprobe test facility
