There are Proteus simulations for ARM7 available online, and if you are interested in Proteus, you probably have downloaded it. Are you unable to open the Proteus simulation like I am? Are you encountering the following issues:

[U1_ARMCORE] Read a total of 1732 bytes from file ‘ADS\SENDSTR_Data\DebugRel\test.hex’.
[U1_SYSCON] Memory configuration: 128KB ROM, 16KB RAM
ERROR: [U1_VM2] ‘1.8V VCore’ (2.73V) is outside the specified range (1.65V-1.95V). Real Time Simulation failed to start.
Totaliters=0, Totalsteps=1, Goodsteps=1, Badsteps=0
Real Time Simulation FAILED.
If you look closely, you’ll understand that the issue is indicating that the voltage is incorrect.
So how do we solve it?
Step 1
Step 2
Step 3
Hehe, try again, is it working now?
