Syntax

hdlc = hdlcosim
hdlc = hdlcosim('HDLSimulator',Simulator)
hdlc = hdlcosim('HDLSimulator','Vivado Simulator')
hdlc = hdlcosim(___, Name,Value)

Description

hdlc = hdlcosim creates an hdlverifier.HDLCosimulation System object™ with default properties. This System object provides an interface to your HDL simulation in your MATLAB® workspace.

hdlc = hdlcosim('HDLSimulator',Simulator) creates an hdlverifier.HDLCosimulation to use with HDL simulator of choice and default properties.

example

hdlc = hdlcosim('HDLSimulator','Vivado Simulator') creates an hdlverifier.VivadoHDLCosimulation System object with default properties.

example

hdlc = hdlcosim(___, Name,Value) specifies additional properties using one or more name-value arguments.

Create a System object to use with Synopsys® VCS®. Set input and output signals, and specify a socket connection with port number 1234.

To run a cosimulation, see Verify Viterbi Decoder Using MATLAB System Object and HDL Simulator.

hdlc = hdlcosim('HDLSimulator','VCS', ... 
              'InputSignals', {'/viterbi_block/In1','/viterbi_block/In2'}, ...
              'OutputSignals', {'/viterbi_block/Out1'}, ...
              'OutputSigned', false, ...
              'OutputFractionLengths', 0, ...
              'Connection', {'Socket',1234}, ...
              'PreRunTime', {10,'ns'}, ...
              'SampleTime', {10,'ns'});

Create a System object to use with the Vivado® simulator. Set input and output signals, and specify XSI data.

To run a cosimulation, see Verify Viterbi Decoder Using MATLAB System Object and HDL Simulator.

obj = hdlcosim( ...
  'HDLSimulator', 'Vivado Simulator', ...
  'InputSignals', {'/viterbi_block/In1','/viterbi_block/In2'}, ...
  'OutputSignals', {'/viterbi_block/Out1'}, ...
  'OutputSigned', false, ...
  'OutputDataTypes', {'fixedpoint'}, ...
  'OutputFractionLengths', 0, ...
  'ClockResetSignals',{'/viterbi_block/clk' '/viterbi_block/reset' '/viterbi_block/clk_enable'},...
  'ClockResetTypes', {'Active Rising Edge Clock' 'Step 1 to 0' 'Step 0 to 1' }, ...
  'ClockResetTimes', {{10,'ps'} {8,'ps'} {1,'ps'} }, ...
  'PreRunTime', {0,'ps'}, ...
  'SampleTime', {10,'ps'}, ...
  'XSIData', xsiData);

Note

To configure and create a System object for the Vivado simulator, use the Cosimulation Wizard.

Input Arguments

collapse all

HDL simulator for cosimulation, specified as one of the following:

Name-Value Arguments

Specify optional pairs of arguments as Name1,Value1,...,NameN,ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: hdlc = hdlcosim('HDLSimulator','Vivado Simulator','InputSignals','in1')

For a complete list of property names and values, see the properties of the returned System object, HDLCosimulation or VivadoHDLCosimulation.

Output Arguments
