9 / 143 page  40MX and 42MX FPGA Families 1-5 Revision 12 Antifuse Structures An antifuse is a "normally open" structure. The use of antifuses to implement a programmable logic device results in highly testable structures as well as efficient programming algorithms. There are no pre-existing connections; temporary connections can be made using pass transistors. These temporary connections can isolate individual antifuses to be programmed and individual circuit structures to be tested, which can be done before and after programming. For instance, all metal tracks can be tested for continuity and shorts between adjacent tracks, and the functionality of all logic modules can be verified. Clock Networks The 40MX devices have one global clock distribution network (CLK). A signal can be put on the CLK network by being routed through the CLKBUF buffer. In 42MX devices, there are two low-skew, high-fanout clock distribution networks, referred to as CLKA and CLKB. Each network has a clock module (CLKMOD) that can select the source of the clock signal from any of the following (Figure 1-7 on page 1-6): • Externally from the CLKA pad, using CLKBUF buffer • Externally from the CLKB pad, using CLKBUF buffer • Internally from the CLKINTA input, using CLKINT buffer • Internally from the CLKINTB input, using CLKINT buffer 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. Clock input pads in both 40MX and 42MX devices can also be used as normal I/Os, bypassing the clock networks. The A42MX36 device has four additional register control resources, called quadrant clock networks (Figure 1-8 on page 1-6). 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.
