1. A device, comprising: one or more processors to: provide, via a user interface, information that identifies a plurality of blocks included in a block diagram model; receive a selection of one or more blocks of the plurality of blocks; provide, via the user interface, information that identifies a plurality of parameters that control a behavior of the selected one or more blocks; receive a selection of one or more parameters of the plurality of parameters; create a dialog box that includes the selected one or more parameters, the dialog box permitting editing of values associated with the selected one or more parameters, the dialog box not permitting editing of values associated with parameters other than the selected one or more parameters; generate a masked block, associated with the dialog box, based on the selected one or more parameters; and provide the masked block for display.
9. The device of claim 1 , where the one or more processors are further to: provide, via the user interface, a first input mechanism for providing all of the plurality of parameters in the dialog box; provide, via the user interface, a second input mechanism for providing less than all of the plurality of parameters in the dialog box; and where the one or more processors, when creating the dialog box, are further to: provide all of the plurality of parameters in the dialog box based on detecting an interaction with the first input mechanism, or provide less than all of the plurality of parameters in the dialog box based on detecting an interaction with the second input mechanism.
