6.4. Test interface driver

The test interface driver (Ticbox) is an external module which drives the test interface lines to gain access to the AHB bus, and then applies test vectors from a test input file. This test input file is the output from a C program written with the TICTalk command language.

Before reading this section, you should be familiar with AMBA and its test interface protocol. If not, see the AMBA Specification for more information. Figure 6.4 shows an interface diagram of the ticbox module.
