This appears in Verilog-to-Routing (VTR) or ABC tools — the feature is:
rusec = "routing usage in microseconds" or "resource usage sec" (rare). genlibrusec
More likely: you want to generate a library with proper timing constraints in microseconds (µs) for soft processors. This appears in Verilog-to-Routing (VTR) or ABC tools
To understand GenLibRusEc, you must understand the "Serials Crisis." Since the 1980s, academic journal prices have risen at 300% the rate of inflation. Publishers like Elsevier, Springer, and Wiley charge libraries thousands of dollars per journal edition. Universities pay millions annually; independent researchers pay $30–$50 per single article.

In the early 2000s, a group of technologists and activists—primarily from Russia and China—decided to circumvent this system. Inspired by Aaron Swartz (the internet activist who downloaded millions of JSTOR articles to make them free), they built a bot network to scrape repositories.
