PLECS 1.3 Online Help

Controlling Access to Circuits and Subcircuits

PLECS allows you to control user access to individual subcircuits or to complete circuits. In particular, you can prevent a user from viewing or modifying a schematic while still allowing the user to simulate a circuit. To change the access settings of a circuit, open the permissions dialog box by choosing Circuit permissions from the File menu. To change the settings of a subcircuit, choose Subcircuit permissions from the Edit menu or from the block's context menu.

You can grant or deny the following privileges:

If you apply access restrictions you will be asked for a password to prevent an unauthorized person from lifting these restrictions. The access settings can only be changed again if the correct password is provided.

Encrypting Circuits and Subcircuits

When PLECS saves a circuit with access restrictions to the Simulink model file, it encrypts the respective sections to protect the circuit description from unauthorized access.
