Abstract

A method for editing a computer-aided design model for developing electronic control units in a design environment, whereby the design model comprises at least one model object with first data. The method begins with the reading of all model objects of the design model and the reading of an allocation list, which assigns a particular globally unique key to each model object. If the first data are available, the reading of the first data from a first memory location follows. Then, assignment of the first data to the model object based on the globally unique key occurs, so that the first data are available during editing of the design model. If the first data are not available, assignment of the globally unique key to the model object occurs, so that the globally unique key is available during tediting of the design model.

Claims

1. A method for editing a computer-aided design model for developing electronic control units in a design environment, the design model comprises at least one model object with first data, the first data being additional data that are used only for individual development steps of the control device, the method comprising:

reading all model objects of the design model in the development environment;

reading an allocation list that assigns a particular globally unique key to each model object;

determining whether the first data are available,

if the first data are available;

reading the first data from a first memory location, wherein the first data contain the globally unique key, and then the first data are assigned to the model object based on the global unique key, so that the first data are available during editing of the design model, or

if the first data are not available;

assigning the globally unique key to the model object so that the globally unique key is available during the editing of the design model;

editing of the design model; and

saving the allocation list in which the globally unique key is assigned to the model object, the step of saving comprises;

if the first data are available during the editing, generating a new globally unique key, which replaces the previous globally unique key;

if the first data are not available during editing, retaining the globally unique key;

saving the first data together with the globally unique key; and

saving all model objects of the design model.

2. The method according to claim 1, wherein the first data are not available, if

(i) the first data does not exist;

(ii) the first data are protected by a password;

or

(iii) the first data are protected by an access authorization.

3. The method according to claim 1, wherein the allocation list defines access authorization for different users or user groups, and wherein the step of assigning the first data to the model object, if the first data does exist, comprises:

checking a user'"'"'s access authorization for the first data;

if the user has access rights, assigning the first data to the model object, so that the first data are available during editing of the design model; and

if there are no access rights, assigning the globally unique key to the model object, so that only the globally unique key is available during editing of the design model.

4. The method according to claim 1, wherein the step of reading of all model objects of the design model in the development environment comprises creating and reading the first model object from a model library;

and wherein the step of reading an allocation list, which assigns a globally unique key to the model object, comprises reading an allocation list associated with the model object from the model library, which assigns a globally unique key to the model object.

5. The method according to claim 4, wherein the model object is assigned its own unique global key or wherein the model object receives the global key of the model library object.
