Picture Perfect Results with Verdi & Siloti
Product:
Video compression and imaging processing chips
Challenges:
-
Strict time-to-market schedule
-
Simulation of large streams of data
-
Waveform data dumping takes weeks
Why Verdi?:
-
Provides ability to understand someone else's work
-
Allows automated tracing of design behavior over multiple clock cycles that reduced debug time
-
Significant performance and efficiency at RTL level debug
-
Ability to debug memory elements faster, saving value time in their overall verification scheduled
"Verdi probably saved us 50 percent in overall debug time, which is extremely beneficial in terms of giving us time to run more tests. It’s what gets us the most bang for the buck, by increasing the confidence level that we are going to get clean silicon,” - Rudi Rughoonundon, Senior Engineer, Ambarella
Why Siloti?:
- Eliminates the overhead associated with dumping data for all the signals in their designs
- Provides full visibility of internal signals by identifying the minimal “essential” set if signal required for dumping
- Generates the minimal list of signals for dumping
“This resulted in a much more thorough and efficient verification process with no loss in visibility during debug, thanks to the Siloti capability for on-demand data expansion (DE) within the Verdi debug environment,” explained Rughoonundon. “We used Siloti at the RTL and gate level, and each time it saved us significant run time. Siloti should win a prize. It’s way ahead of its time.” - Rudi Rughoonundon, Senior Engineer, Ambarella
DRC Uses Verdi Debug to Accelerate Development Time of High Performance Reconfigurable Co-processor
Product:
RPU Accelerator for AMD Opteron CPU
Challenges:
