LED
Green Status LED
The red LED is the power indicator LED. This will be lit if power on the ICE50 is turned
on and the power system is working correctly. If the LED stays off after power on, make
sure the power supply meets the requirements of the ICE50. If using another power sup-
ply than the one supplied with the ICE50 make sure that the power polarity is correct.
See the Power System section for more details on power requirements.
The Multicolor LED displays information about which mode the ICE50 is working in. Dur-
ing the startup sequence this LED is first red, next orange. Orange indicates that the
Emulator is in stopped mode. A green light indicates that the ICE is in run mode. If the
LED turns red it indicates an emulator error. If this happens consult the troubleshooting
guide.
The green LED will be turned on when the ICE50 is ready for emulation. Once the green
LED is on, the ICE50 is ready for emulation. The LED will flash during upgrading of the
ICE50. The LED will be turned off during loading of a new part, and lit when the part is
finished loading. If the LED does not turn on after a power up sequence please consult
the troubleshooting guide for possible solutions.
