Design and implementation of a suitable core for on-chip long-term verification
Traditional on-chip and off-chip logic analyzers
present important shortcomings when used for the long-term
verification of industrial embedded systems, forcing the designer
to implement ad-hoc verification solutions. This contribution
presents a suitable solution for long-term verification of FPGAbased
designs consisting on a verification core that uses the
Picoblaze microcontroller, dedicated logic and a serial port
communication in order to monitor the internal signals of the
system in a continuous way. The core design focuses on low
resource requirements and reusability and has been successfully
applied to the verification of a real industrial synchronization
platform showing remarkable advantages over commercial onchip
