1. DARPA A Metrics System for Continuous Improvement of Design Technology Andrew B. Kahng and Stefanus Mantik

2. 2 06/04/00 Current Status u Complete prototype of METRICS with industry standard components (Oracle, Java, XML, HTML, etc.) u Metricized Place and Route runs on 100+ designs, seeking access to Synopsys regression suite data u Complete metricization of Cadence system-level timing flow u Metricization of synthesis and verilog simulation tools u Initial feedback from industry on METRICS standards u Attempting to spec Intel requirements for METRICS system

3. 3 06/04/00 COM-Based Alternative u EDA tools: s provide COM interface for capturing internal information s add information collections (“counters”) inside the tools u METRICS transmitter: s get information via the COM interface s format the data in XML, encrypt the message, and send it to the server u Benefit: s allow independent development for transmitter and tools

4. 4 06/04/00 Current Results u CPU_TIME = 12 + 0.027 NUM_CELLS (correlation = 0.93) u More plots are accessible at http://xenon.cs.ucla.edu:8080/metrics
