Reset input port

Name for reset input port

Model Configuration Pane: Global Settings

Description

Enter the name for the reset input port in generated HDL code.

Dependencies

If you specify active-high for Reset asserted level, the reset input signal is asserted active-high. To reset the registers in the entity, the input value to the Reset input port must be high. If you specify active-low for Reset asserted level, the reset input signal is asserted active-low. To reset the registers in the entity, the input value to the Reset input port must be low.

Settings

reset (default) | character vector

Default: reset

Enter a character vector for the reset input port name in generated HDL code.

For example, if you override the default with 'chip_reset' for the generating system myfilter, the generated entity declaration might look as follows:

ENTITY myfilter IS
   PORT( clk             :  IN  std_logic;
         clk_enable      :  IN  std_logic;
         chip_reset      :  IN  std_logic;
         myfilter_in     :  IN  std_logic_vector (15 DOWNTO 0); 
         myfilter_out    :  OUT std_logic_vector (15 DOWNTO 0); 
         );
END myfilter;

If you specify a VHDL®, Verilog® or SystemVerilog reserved word, the code generator appends a reserved word postfix string to form a valid VHDL, Verilog or SystemVerilog identifier. For example, if you specify the reserved word signal, the resulting name string would be signal_rsvd.

Tips

To set this property, use the functions hdlset_param or makehdl. To view the property value, use the function hdlget_param.

For example, you can specify sync as the ResetType when you generate HDL code for the symmetric_fir subsystem inside the sfir_fixed model using either of these methods.

  • Pass the property as an argument to the makehdl function.

    makehdl('sfir_fixed/symmetric_fir', ... 
        'ResetInputPort','rstx')

  • When you use hdlset_param, you can set the parameter on the model and then generate HDL code using makehdl.

    hdlset_param('sfir_fixed','ResetInputPort','rstx')
makehdl('sfir_fixed/symmetric_fir')
