* The vvm environment supports external calls to C++ by
|

* vvm_calltask. The code generator generates calls to vvm_calltask
|
||
|
|
* that corresponds to the system call in the Verilog source. The
|
||
|
|
* vvm_calltask in turn locates the function (by name) and calls the
|
||
|
|
* C++ code that implements the task.
|
||
|
|
*
|
||
|
|
* The parameters of the task are implemented as an array of
|
||
|
|
* vvm_calltf_parm objects. Each object represents a paramter from the
|
||
|
|
* source.
