  The ever-increasing architectural complexity in contemporary ASIC projects
turns Design Verification (DV) into a highly advanced endeavor. Pressing needs
for short time-to-market has made automation a key solution in DV. However,
recurring execution of large regression suites inevitably leads to challenging
amounts of test results. Following the design science paradigm, we present an
action research study to introduce visual analytics in a commercial ASIC
project. We develop a cityscape visualization tool using the game engine Unity.
Initial evaluations are promising, suggesting that the tool offers a novel
approach to identify error-prone parts of the design, as well as coverage
holes.
