cvsimref - Simulate and return model coverage results for referenced models

Syntax

Description

cvdg = cvsimref(topModelName) simulates the top model and all referenced models in the hierarchy, collects model coverage data, and returns the results in the cv.cvdatagroup object cvdg. You do not have to enable model coverage reporting for any of the models in a model hierarchy to use the cvsimref command.

cvdg = cvsimref(topModelName, cvtg) simulates topModelName and collects model coverage data by executing the cv.cvtestgroup object cvtg. cvtg contains cvtest specifications for the top-level model and all the referenced models in the hierarchy. cvsimref returns the model coverage results in cvdg.

[cvdg,t,x,y] = cvsimref(topModelName, cvtg) returns the time vector t, matrix of state values x, and matrix of output values y from the simulation.

[cvdg,t,x,y] = cvsimref(topModelName, cvtg, timespan, options) overrides default simulation values with the values in timespan and options.

[cvdg1, cvdg2, ...] = cvsimref(topModelName, cvtg1, cvtg2, ...) executes multiple cv.cvtestgroup objects and returns the results in a set of cv.cvdatagroup objects.

Input Arguments

cvtg	cv.cvtestgroup object that contains test specifications for the referenced models in the hierarchy
options	Optional simulation parameters specified as a structure.
timespan	Simulation start and stop time: tFinal Specify the stop time. The start time is 0. [tStart tFinal] Specify the start and stop times. [tStart OutputTimes tFinal] Specify that cvsimref return the start and stop times and time points in t. Generally, t includes more time points. OutputTimes is equivalent to specifying Configuration Parameters > Data Import/Export > Output options > Produce specified output only.
topModelName	Name of the top-level model in the hierarchy

Output Arguments

cvdg	cv.cvdatagroup object

t	The simulation time vector
x	The simulation state matrix consisting of continuous states followed by discrete states

y	The simulation output matrix. Each column contains the output of a root-level Outport block, in port number order. If any Outport block has a vector input, its output has the associated number of columns.

Examples

Open and simulate the slvnvdemo_ratelim_harness model and its two subsystems:

topModel = 'slvnvdemo_cv_mutual_exclusion';
load_system(topModel);
% Make sure coverage is off for this run for the entire tree
set_param(topModel,'RecordCoverage','off');
set_param(topModel,'CovModelRefEnable','Off');
simObj = sim(topModel);                  % Normal data
allData = cvsimref(topModel);            % cvsimref data
