This enhancement has been incorporated in Release 2008a (R2008a). For previous product releases, read below for any possible workarounds:
Real-Time Workshop does not require any specific hardware. It is an open environment that allows you to run on any type of system by writing drivers to interface to that system. Real-Time Workshop ships device drivers for specific systems; however, you are not limited to these drivers. You can use the shipped drivers as templates to configure your system with Real-Time Workshop.
We have two products available that allow you to use your Real-Time Workshop generated code with PC hardware. Real-Time Windows Target is a single PC Windows target for C code generated by Real-Time Workshop. It is ideal for real-time control, real-time signal processing, rapid prototyping, hardware-in-the-loop testing, and other applications. For more information, please see the following URL:

xPC Target allows you to add I/O blocks to your Simulink block diagrams, generate code with Real-Time Workshop, and download the code to a second PC that runs the xPC Target real-time kernel. xPC Target is ideal for rapid prototyping and hardware-in-the-loop testing of control and DSP systems. It allows you to execute models in real time on standard PC hardware. For more information on this product, see the following URL:

If you are not using one of the above mentioned systems, relevant information is provided in the Real-Time Workshop documentation, in the Customizing Targets section. This information can be accessed online at the following URL:
