A.1. IR length configuration file

Multi-ICE must calculate the length of the scan chain it is connected to. It does this by adding the length of each TAP IR register it finds in the scan chain. This is possible by identifying the devices in the chain and using information in a file called IRlength.arm. This file is stored in the Multi-ICE installation directory. An extract from the IRlength.arm file is shown in Example A.1.
