From gui/StartupOptions.java:
| -h | help flag displays command line options |
| -de FILENAME | allows design file name to be specified |
| -di DIRECTORY | allows design directory to be specified |
| -do FILENAME | allows output file name to be specified |
| -dr FILENAME | allows design rules file name to be specified |
| -fo | pre-route fanout true. Off by default. |
| -ap INTEGER | allows maximum batch autorouter passes to be specified; should be 2 or more. |
| -pp INTEGER | allows maximum post route optimising passes to be specified. Off by default. |
| -mt INTEGER | number of threads for postroute optimisation range(1, #cores-1), default #cores-1 |
| -oit FLOAT | stops the postroute optimizer if improvement drops below a certain percentage threshold per pass. Default is 0.1%, and 0% means to continue improving until there are no more route options to test |
| -us [greedy|global|hybrid] | sets board updating strategy for route optimization: greedy, global optimal or hybrid. The default is greedy. When hybrid is selected, another option "hr" specifies hybrid ratio. |
| -hr INTEGER:INTEGER | sets hybrid ratio in the format of #_global_optiomal_passes:#_prioritized_passes. The default is 1:1. It's only effective when hybrid strategy is selected. |
| -is [sequential|random|prioritized] | sets item selection strategy for route optimization: sequential, random, prioritized. The default is prioritized. Prioritied stragegy selects items based on scores calculated in previous round. |
| -test | testing mode true (to enable experimental features). Off by default. |
| -trace INTEGER | default value 0 (no debug output), 1 critical debug info, 2 all debug info |
example usage:
