Function Documentation

verilog_tf_funcSig

(

vlog_ruby_init

)

Callback for the $ruby_init VPI task.

Initializes and starts the Ruby interpreter with the same arguments as those given to the VPI task-call.

For example, to start the Ruby interpreter with the "-w" option and with the "hello_world.rb" script, the Verilog code would have a statement like this:

• $ruby_init("-w", "hello_world.rb");

verilog_tf_funcSig

(

vlog_ruby_relay

)

Callback for the $ruby_relay VPI task.

Transfers control from Verilog to Ruby code.

void vlog_bind_task	(	PLI_BYTE8 *	apTaskName,
		verilog_tf_funcPtr(apTaskDef)
	)

Binds a C function to a VPI task, so that Verilog code can invoke the C function by calling the VPI task.

For example, if we bound a VPI task named "$hello_world" to the C function hello_world(), then the hello_world() function would be invoked whenever Verilog code called the "$hello_world" VPI task.

Parameters:

	apTaskName	Name of the VPI task. For example, "$hello_world".
	apTaskDef	The C function which you want to associate with the given VPI task. For example, hello_world().
