matlabtb

Specify for HDL Verifier to use TCP/IP sockets to communicate between the HDL simulator and MATLAB. Shared memory is the default mode of communication and takes effect if you do not specify -socket <tcp_spec>. The communication mode that you specify with the matlabtb command must match the communication mode that you specified with the hdldaemon command.

For more information on choosing TCP/IP socket ports, see TCP/IP Socket Ports.

Specify -rising with the path names of one or more signals defined as a logic type (STD_LOGIC, BIT, X01, and so on).This pair indicates that the application calls the specified MATLAB function on the rising edge (transition from '0' to '1') of any of the specified signals.

Specify the path names of one or more signals defined as a logic type (STD_LOGIC, BIT, X01, and so on). Indicates that the application calls the specified MATLAB function whenever any of the specified signals experience a falling edge(a transition from '1' to '0').

For determining signal transition in:

Specify the path names of one or more signals. This pair indicates that the application calls the specified MATLAB function whenever any of the specified signals change state. Signals of any type can appear in the sensitivity list and can be positioned at any level in the HDL model hierarchy.

Specify the name of the MATLAB function that is associated with the HDL module instance you specify for instance. By default, the HDL Verifier software calls a MATLAB function that has the same name as the specified HDL instance. If the names are the same, you can omit the -mfunc pair. If the names are not the same, use this argument when you call matlabtb. If you omit this argument and matlabtb does not find a MATLAB function with the same name, the command generates an error message.

This pair Instructs the function specified with the argument -mfunc to use an HDL instance object passed by HDL Verifier to the function. This value has the fields shown in the applicable table. See Writing Functions Using the HDL Instance Object for examples.

Pass user-defined arguments from the matlabtb command on the HDL side to the MATLAB function callbacks. This pair is supported with -use_instance_obj only. For more details, see the field in the table -use_instance_obj Fields.

Schedule a callback during the set time. This field is equivalent to old tnext. For example, this code schedules a callback 5 nanoseconds from tnow.

hdl_instance_obj.tnext = hdl_instance_obj.tnow + 5e-9

Store the status of the HDL simulator. The HDL Verifier software sets this field to Init during the first callback for this particular instance and to Running thereafter. simstatus is a read-only field.

>> hdl_instance_obj.simstatus

ans=
      Init

Store the full path of the Verilog or VHDL instance associated with the callback. instance is a read-only field. The value of this field equals that of the module instance specified with the function call. For example:

In the HDL simulator:

hdlsim> matlabtb osc_top -mfunc oscfilter use_instance_obj

In MATLAB:

>> hdl_instance_obj.instance

ans=
		osc_top

Store the argument that is set by the -argument pair. For example:

matlabtb osc_top -mfunc oscfilter -use_instance_obj -argument foo

>> hdl_instance_obj.argument

ans= 
    	foo

Store information about the VHDL and Verilog ports that are associated with this instance. portinfo is a read-only property, which has a field structure that describes the ports defined for the associated HDL module. For each port, the portinfo structure passes information such as the type, direction, and size of the port. For more information on port data, see Gaining Access to and Applying Port Information.

hdl_instance_obj.portinfo.field1.field2.field3

Store the resolution limit (tick) in seconds of the HDL simulator. tscale is a read-only property.

>> hdl_instance_obj.tscale

ans=
	1.0000e-009

Store the current time. tnow is a read-only property.

hdl_instance_obj.tnext = hld_instance_obj.tnow + fastestrate;

Store the current values of and set new values for the output and input ports for a matlabtb instance. For example:

>> hdl_instance_obj.portvalues

ans =
Read Only Input ports:
	clk_enable: []
	clk: []
	reset: []
Read/Write Output ports:
	sine_out: [22x1 char]

Store the status of the callback. HDL Verifier sets this field to 'testbench' if the callback is associated with the matlabtb command and 'component' if the callback is associated with the matlabcp command. linkmode is a read-only property.

>> hdl_instance_obj.linkmode

ans=
	component
