Syntax | set_scc_mode [-h | -help] [-long_help] [-size <size> ] [-use_heuristic] | ||
Arguments | -h | -help | Short help | |
-long_help | Long help with examples and possible return values | ||
-size <size> | Maximum SCC loop size | ||
-use_heuristic | Always use heuristic for SCC processing | ||
Description | Allows you to set maximum Strongly Connected Components (SCC) loop size or force the Timing Analyzer to always estimate delays through SCCs. When the Timing Analyzer encounters a loop of size greater than the specified maximum SCC loop size, it uses a heuristic which only estimates delays through the loop. If the loop is smaller than the maximum SCC loop size, a full processing of loops is performed unless the -use_heuristic option is used. |
