Cogita Success Story
Company-X develops complex ASICs and FPGA that facilitate massive traffic from CPUs to memory.
Company-X verification team inferred from previous projects that such a subsystem verification will take 10 months for 4 engineers.
We explain the main functionality of the DUT and testbench and the challenges in debugging that Cogita, later on, was able to solve.
Hardware-Software Co-Verification Debugging
In every complex SoC verification process, it is necessary to activate the CPUs during verification and to check the operation of the software they execute alongside the test’s scenarios. At a minimum, basic scenarios such as “boot rom execution” are tested, but in many cases, further scenarios are required. The CPUs themselves are usually proven IPs, but in order to verify their integration and operation within the SoC, it is not enough to connect a VIP to the CPU bus and have it imitate the CPU’s behavior.
Debugging Debug
While semiconductor verification techniques have evolved considerably over the last 25 years, the debug of design problems found during verification has barely changed. New algorithms including machine learning, visualization approaches, and problem solving ideas allow a different approach to debug that saves up to an order of magnitude in debug time.
