Abstract: A system and method for operating a high-performance learning-ready platform for real-time analytics involves operating a collector to collect logging data from electronic design automation (EDA) tools. The collector operates either (A) a set of programming interface (i.e., function calls) integrated with an EDA tool, or (B) a selector to extract the logging data from EDA tool logs. The collector generates data logs in a key-value pair data logging format from the logging data. A memory controller loads and indexes the data logs into a controlled memory data structure. A comparator in an archiving engine prioritizes storage of particular data logs based, in part, on previously stored data logs in the controlled memory data structure.
