Какая версия quartus-а пригодна для работы со stratix?
Смысл текста внизу такой - есть 8 светодиодов, 4 средние выключены, 2 слева и 2 справа включены.
Синтезатор честно предупреждает, все как и положено:
Warning: Output pins are stuck at VCC or GND
Warning: Pin "USER_LED[0]" stuck at VCC
Warning: Pin "USER_LED[1]" stuck at VCC
Warning: Pin "USER_LED[2]" stuck at GND
Warning: Pin "USER_LED[3]" stuck at GND
Warning: Pin "USER_LED[4]" stuck at GND
Warning: Pin "USER_LED[5]" stuck at GND
Warning: Pin "USER_LED[6]" stuck at VCC
Warning: Pin "USER_LED[7]" stuck at VCC
А фитер, молодец, все на GND подключил и еще ехидничает:
Warning: Following 8 pins have nothing, GND, or VCC driving datain port -- changes to this connectivity may change fitting results
Info: Pin USER_LED[0] has GND driving its datain port
Info: Pin USER_LED[1] has GND driving its datain port
Info: Pin USER_LED[2] has GND driving its datain port
Info: Pin USER_LED[3] has GND driving its datain port
Info: Pin USER_LED[4] has GND driving its datain port
Info: Pin USER_LED[5] has GND driving its datain port
Info: Pin USER_LED[6] has GND driving its datain port
Info: Pin USER_LED[7] has GND driving its datain port
Табуляции заменены на подчерк.
