What JHDL Provides

In addition to these specific design aids, JHDL provides a unified design environment where a single, user interface can be used for both simulation and execution. This allows the designer to request either simulation or execution (or a mixture of the two) using the exact same commands for both.

For example, within this unified environment, commands such as set-breakpoint, examine-variable, single-step, etc., are the same whether performing simulation or execution. This is a big advantage for designers because they can learn a single debugging environment that works for both simulation and execution --in contrast with current systems where execution and simulation environments are distinct and very different.

Moreover, this is what makes it possible to use the same program for both software simulation and hardware execution. Design views are unified as well; for example, the schematic view can display either simulated values or values retrieved from the FPGA platform during execution using the same view and interface.
