Chapter 4

Differences between Target Device and Emulation Board

When the In-Circuit-Emulator is connected to a target system for debugging, the V850ES/GB1 is emu-
lated which means that the emulator behaves like the real chip in the target system. Small differences
occur however. This chapter lists differences between the emulation system and the V850ES/GB1.

4.1  BCU (bus control unit)

The BCU is established within an FPGA. Therefore this could be slightly different to the real chip.

4.2  Load on voltage supply pins

The I/O chip is supplied by a power supply on the emulation board. Therefore the load on the power
supply of the target board is very low compared to the real chip.

4.3 Reset 

input

The reset pin of the target connector is not connected to the reset pin of the I/O chip directly. It also has
got a 10 K

Ω

 pull-up resistor connected to it. The input characteristic differs from the real chip.

4.4 REGC 

pin

The REGC pin of the target connector is not connected to the corresponding pin of the I/O chip. On the
emulation board a capacitor is connected to the REGC pin of the I/O chip internally.

4.5 Clock 

oscillator 

inputs

The pins for main clock connection (X1 and X2) as well as the pins for sub clock connection (CL1, CL2
/ XT1, XT2) of the I/O chip on the emulation board are not connected to the target connector. If a crystal
is to be used for the clock generator it must be connected to the respective connector on the emulation
board which is located electrically close to the I/O chip. Crystal operation from the target board is not
possible. Alternatively a dedicated C-MOS oscillator can be used for the main clock and a timer circuit
provided on the emulation board can be used for the sub clock (See also 2.5 Clock 

Operation).

4.6 V

PP

 pin

V

PP

 pin of the I/O chip on the emulation board is connected to the target connector with a load of 

10 K

Ω

 (series resistor). On the emulation board it is only monitored and not used internally. Correct

connection on the target board must be assured.
