HwPMI: An Extensible Performance Monitoring Infrastructure for Improving Hardware Design and Productivity on FPGAs

Figure 1

Torc’s Generic Netlist API I/O Performance. This log-log plot shows reasonably linear I/O performance for EDIF file sizes ranging from 1 KB to 175 MB. On a 2.8 GHz quad-core Xeon, the API reads 45-thousand lines per second, and 2.3 Megabytes per second on average. The largest of these files contains over 150,000 instances and over 200,000 nets. Shape differences between the two curves are most likely due to different name lengths in the EDIF files.
