CubeSuite+ Simulator for V850E2 supporting OS Timer V3.02.00 Release Note R20UT2916EJ0100 Rev.1.00 Page 5 of 9 February 17, 2014 Chapter 4. Cautions This section describes cautions for using the V850E2 supporting OS Timer simulator. The following two types of caution are described.
- Cautions for CPU core function
- Cautions for OS Timer
4.1 Cautions for CPU core function
4.1.1 CPU function
The simulator supports as following functions. Other functions are not supported. - CPU instruction - Exceptions - System register protection - Memory protection - Timing supervision function - Floating-point operation function
4.1.2 External memory bus
The access to external memory area is not supported.
4.1.3 Floating-point unit
A simulation result of the floating -point unit [FPU] has a margin of errors compared to real devices. The simulator uses the floating-point library of Visual C++, and store a result calculated by 80bit in a register.
4.1.4 Exceptions
Following exception is not supported. System error exception, Memory error exception
4.1.5 Cache memory
The simulation of cache memory is not supported.

4.1.6 Instructions
The instructions (SYNCE/SYNCM/SYNCP) are not supported. If these were executed, the operation is same as NOP execution.
4.1.7 Data flash
It is impossible to use data flash area. If CPU accesses this area, CPU breaks and error is happen.
4.1.8 Option byte storage register
The value of Option byte storage register "OPBT0" is always "0".
4.1.9 EH_RESET register function
EH_RESET register functions are not supported. In the case of a CPU reset, the reset address will always be "0x0".
4.1.10 CPU clock frequency
The CPU clock frequency is the value which is specified with the [Main clock frequency] property.
4.1.11 Execution clock
The number of execution clocks of each instruction will be the number of execution clocks when another instruction is executed immediately after that instruction is executed.

4.2 Cautions for OS Timer
4.2.1 P-bus peripheral I/O registers
The simulator supports following P-bus peripheral I/O registers for OS timer. Nickname P-bus peripheral I/O registers V850E2/Mx4 ICOSTM0, IMR0, OSTM0CTL, OSTM0CMP, OSTM0CNT, OSTM0TE, OSTM0TS,OSTM0TT V850E2/Dx4 ICOSTM0, IMR9, OSTM0CTL, OSTM0CMP, OSTM0CNT, OSTM0TE, OSTM0TS,OSTM0TT V850E2/Fx4 ICOSTM0, IMR9, OSTM0CTL, OSTM0CMP, OSTM0CNT, OSTM0TE, OSTM0TS,OSTM0TT V850E2/Px4 ICOSTM0, ICOSTM1, IMR2, OSTM0CTL, OSTM1CTL, OSTM0CMP, OSTM1CMP, OSTM0CNT, OSTM1CNT, OSTM0TE, OSTM1TE, OSTM0TS, OSTM1TS, OSTM0TT, OSTM1TT
4.2.2 The count clock of OS Timer
The count clock of OSTM is decided by the Option Byte value. It's possible to refer to the Option Byte value in CubeSuite+ property. Please specify the value in bit4,bit3 as follows. Even if bit4,bit3 of Option Byte of the selected device have the different feature, these bits are used to decide the count clock of OSTM by CubeSuite+ Simulator for V850E2 supporting OS Timer. bit4 bit3 0 0 equal to CPUCLK 0 1 CPUCLK/2 1 0 CPUCLK/4 1 1 Setting prohibited (By CubeSuite+ Simulator, CPUCLK/4)

4.3 Cautions for Prism of Critical Blue
4.3.1 Cooperation of CubeSuite+simulator and Prism
The PEP which is included on the Prism package generates Prism information files (PGTS file and PGTI file) from LM file. On the next step, prepare smplus_prism.ini which contains PGTS file and PGT file information. CubeSuite+simulator will generate the Prism trace file based on smplus_prism.ini description by executing a LM file. An analysis by the Prism is available on the above process.
4.3.2 Supported compiler
Only GHS compiler is supported. To analyze on Prism, please specify “-G –dual_debug” options for compiler.
4.3.3 Supported device
Only uPD70F3510 and 3512 are supported. 4.3.4 About .ini file When the smplus_prism.ini exists in the same folder as CubeSuite+ project file or project subfolder, and description of the file is correct, the CubeSuite+simulator will generate a trace file for the Prism. If there are plural smplus_prism.ini files, the simulator reads the file from the most upper level sub folder. Please write PGT file and PGTS file informations in the smplus_prism.ini. A maximum file name length is 255 characters including path. The smplus_prism.ini has to have full path information of files even if the files are on the project folder. In case of tracing program which uses RI850V4, smplus_prism.ini has to contain an address information for “__kernel_trace_data”. The following is an example of smplus_prism.ini.

4.3.5 Reexecution after Reset
When executing one time and reexecuting after reset, CubeSuite+ ends. Please don't reexecute after a reset.
4.3.6 Cycle numbers after stopping at break point
If a program execution is stopped by a break point during Prism Trace File generating, the cycle number displayed on the prism will be increased by number of times which stopped at break point. But this behavior does not happen when at least one of the following functions are used. Hardware break point by access event. Timer-function. Ttrace-function. A coverage-function.
