Clifford Wolf e92998a79c Minor bugfix in FSM reset state detection 2016-07-12 09:46:15 +02:00
Clifford Wolf b5a9fba0db Further improved fsm_detect output, attempt to detect self-resetting circuits 2016-07-09 14:02:49 +02:00

Clifford Wolf 6ed6b3cb6d Replaced "select -assert-limit" with -assert-max and -assert-min 2016-07-01 12:24:13 +02:00
eshellko 9a742f4069 Added 'assert-limit' option for 'select' command 
For resource limited designs such as FPGA it can be useful to specify limit of specific resources available on board. So user can check if he should change RTL as early as mapping done.
