I compiled my Design with the new version 6.0 of Quartus and get much more Warnings :-( Especially a Critical Warning of the Fitter disconcerts me:
Critical Warning: Ignored Power-Up Level option on the following nodes -- nodes are set to power up low Critical Warning: I/O cell "i2c_core:inst33|i2c_master_top:inst|i2c_master_byte_ctrl:byte_ctrl|i2c_master_bit_ctrl:bit_ctrl|c_state.idle" will power-up low Critical Warning: I/O cell "i2c_control:inst32|i2c_todo.test_i2c" will power-up low Critical Warning: I/O cell "i2c_control:inst32|i2c_state.write_i2c_core_reg" will power-up low Critical Warning: I/O cell "i2c_core:inst33|i2c_master_top:inst|i2c_master_byte_ctrl:byte_ctrl|\statemachine:c_state.st_idle" will power-up low
This I/O cells are the states of the state machines. How can the state machines be in the right state if the power-up level is not correct initialized ??? The new compilation works anyway!!! Can someone explain it to me???
Thanks, Manfred
