CHAPTER 4 DIFFERENCES BETWEEN TARGET INTERFACE CIRCUIT AND TARGET DEVICE
This chapter explains the differences between the signal lines of a target interface circuit of the QB-78K0FX2 and
the signal lines of a target device
Although the target device is a CMOS circuit, the target interface circuit of the QB-78K0FX2 consists of an
emulation circuit that depends on the emulation CPU, TTL, CMOS-IC, or other.
When the target system is debugged by connecting it to the QB-78K0FX2, the QB-78K0FX2 emulates just as if the
actual target device were operating on the target system.
However, small differences arise because the QB-78K0FX2 actually is emulating.
(1) Signals input and output by emulation CPU (FPGA, μ PD78F0893)
(2) Other signals
The circuits of the QB-78K0FX2 for the signals in (1) and (2) above are shown below by target device.
