FPGA realtime logic debug technology cuts verification times

The latest version of Xilinx' realtime debug and verification software for FPGA design, ChipScope Pro 6.2i, takes advantage of the reprogrammable nature of Xilinx FPGAs to deliver flexibility and speed during the logic and embedded systems debug phase of a design. This is a capability that is unavailable in conventional ASIC technology and PLD offerings.
One of the key capabilities in ChipScope Pro 6.2i is the addition of the second-generation Agilent Trace Core (ATC2), which links it to Agilent's 16900, 1690, and 1680 series logic analysers. This unique measurement collaboration results in a faster and more effective way to use logic analysis to debug FPGA-based systems, says Xilinx.
The ATC2 core included with ChipScope Pro 6.2i, enables engineers to capture and analyse on-chip FPGA signals directly with an Agilent logic analyser. Engineers can now configure their FPGA, probe internal FPGA signals at system speed, and correlate them to signals captured elsewhere on the board, using their Agilent logic analyser and a Xilinx programming cable.
ChipScope Pro tools allow engineers to insert ATC2 cores into their FPGA during the design phase, or insert cores to a post-synthesized design netlist. Once in the FPGA, the ATC2 provides logic analysis measurement access on any internal FPGA signal. The new configurable ATC2 core uses up to 32 signal banks, with each signal bank able to support up to 128 signals. With optional 2X pin compression, designers can access up to 8192 internal FPGA signals in realtime.
The Xilinx programming cable then provides the communication link between an Agilent logic analyser running the FPGA Dynamic Probe application and the ATC2 core. All Windows-based Agilent logic analysers support the application.
ChipScope Pro is optional verification software that interfaces directly to Xilinx ISE design software.
