源程序模拟器是在广泛使用的、人机接口完备的工作平台上，如小型机和PC，通过软件手段模拟执行为某种嵌入式处理器内核编写的源程序测试工具。简单的模拟器可以通过指令解释方式逐条执行源程序，分配虚拟存储空间和外设，供程序员检查；高级的模拟器可以利用计算机的外部接口模拟出处理器的I/O电气信号。不同档次和功能模拟器工具价格差距巨大。
模拟器软件独立于处理器硬件，一般与编译器集成在同一个环境中，是一种有效的源程序检验和测试工具。但值得注意的是，模拟器毕竟是以一种处理器模拟另一种处理器的运行，在指令执行时间、中断响应、定时器等方面很可能与实际处理器有相当的差别。另外它无法和ICE一样，仿真嵌入式系统在应用系统中的实际执行情况。
