Altium announces a universal JTAG interface that makes it possible for engineers to use the full LiveDesign capabilities of Altium's Nexar system-level FPGA development software with virtually any third-party FPGA development board. The interface makes it easy for developers to use their existing FPGA development boards to interactively design and debug digital systems, including entire processor-based systems, on an FPGA using Nexar. The universal JTAG interface attaches to the parallel port of a developer's computer and features a set of flying leads that connect to the target development board. The interface supports two independent JTAG connections — one to the JTAG programming pins of the target FPGA and the other to four general I/O pins of the FPGA used to establish a secondary soft JTAG chain inside the device. The soft JTAG chain is used by Nexar to communicate in real-time with active design elements such as its processor cores and virtual instruments in the circuit implemented inside the FPGA, facilitating interactive development and debug of the system.
