A program is executed in an information processing device including a processor and a memory. The program allows the processor to execute a step of, on the basis of a simulation result of a model in the case where a series of blocks having an input block, one or more operation blocks, and an output block are allowed to operate at a predetermined clock frequency, deciding a new clock frequency of a target block that is allowed to operate at a clock frequency lower than the predetermined clock frequency, and a step of setting the conversion ratios of conversion blocks so as to execute a simulation of the model in which the target block is allowed to operate at the new clock frequency lower than the predetermined clock frequency and the remaining blocks are allowed to operate at the predetermined clock frequency.

Program, information processing device, and information processing method

A microcomputer includes a read only memory (ROM) with ROM areas in a built-in ROM for emulation by a random access memory (RAM) for fine tuning a program to be written into the ROM. The microcomputer further includes RAM areas in a built-in RAM and an assigning unit for assigning at least one RAM area to each of the ROM areas. In the emulation mode, each of the ROM areas can be replaced with a corresponding RAM area.
