Reach 200,000 x the visibility of JTAG instrumentation.
Go beyond JTAG
FPGA programmability has traditionally enabled engineers to use board prototypes in the lab for debug and verification. Using a system at speed in its ‘real’ environment is used to overcome modeling errors and excessive simulation times.
However, with the unprecedented complexities reached by FPGAs today, the usual JTAG-based embedded logic analyzers hardly provide sufficient visibility on system-under-test and create tough board implementation constraints.
Scale your tools, not your expectations
Over time, the usual JTAG-based tools and traditional instrumentation have failed to provide the visibility required by increasing FPGA complexities.
Prototyping is still a must, though. Using a prototype provides much faster execution than simulation and reveals the imperfections of the models we use in simulation. Even with methodologies that include code coverage, testbench coverage, UVM, assertions or constrained random stimuli, prototyping should be part of any advanced verification flow. However, prototyping a complex FPGA is a good approach only if you can get a reasonable visibility out of it: once on a board, a chip is fast and essentially opaque.
EXOSTIV solves your FPGA debugging challenge
EXOSTIV provides Gigabyte-range visibility into the FPGA at speed of operation and addresses the challenges of debugging on FPGA prototypes:
– Minimal FPGA resources requirements:
EXOSTIV IP requires FPGA memory resources that do not grow with the size of the capture. No matter if you capture 1 KB or 8 GB, FPGA memory is kept as small as a few kilosamples, positively impacting the usage of routing resources in the FPGA. EXOSTIV Dashboard software provides configuration option that let you fine-tune the resources used by EXOSTIV IP.

– Limited board cost: EXOSTIV requires an access to the FPGA transceivers. The connector can be as small as 6.4 mm x 2.8 mm – much smaller than a traditional JTAG pin header or a logic analyzer probe connector. Existing connectors (FMC, SFP+, QSFP+, SATA,…) can be used temporarily for Exostiv too.

– Limited need to recompile: EXOSTIV IP can be inserted into RTL code or at the netlist level, after synthesis (Xilinx FPGA only). Exostiv Dashboard lets you store and reuse previously generated IPs. It provides live settings on data group selection, trigger and data qualification that enable you to change the capture parameters on the fly without the need to recompile the IP.
