RF Components
Here is a stencil for RF/microwave circuit diagrams. These symbols represent signal flow in radio-frequency circuits. They could be used in conjunction with electronics components from the "Electronics Components" stencil, also on Graffletopia. These symbols are based on a combination of symbols in common use. There is a bias...more
Method Engineering
The Method Engineering stencil contains the shapes used in the method engineering approach of Utrecht University. For more information about (situational) method engineering check the wiki or search for Method Engineering in Google.
Electronics Components
This stencil of circuit components includes equipment and novel components found in a physics lab. Documenting experimental setups in this way has been quite successful. I appreciate the circuit aesthetics of the "Microelectronics" textbook by Sedra and Smith, as well as the visual dictionary of components common in SPICE...more
Entity Relation Diagram (ERD)
Allows you to draw simple Entity Relation Diagrams (the first page). ERDs are useful in the early stages of a project, especially if you are using formal approach such as Structured Systems Analysis and Design Methodology (for which there is a SSADM stencil) or IDEF0. I have added an extension, which allows indices to be...more
Data Flow Diagram (SSADM)
The classic Structured Systems Analysis and Design Methodology by Chris Gane and Trish Sarson. SSADM is better known as Data Flow Diagrams. It is a simple and highly effective systems analysis and design (decomposition) methodology. It uses just four symbols, and it is excellent for communicating with non-technical users. A...more
Data Model (IDEF1X)
Allows you to draw IDEF1X-compliant Data Models (examine all five pages). IDEF1X is a methodology and standard (NIST/FIPS 184 in 1993) for modelling Relational databases. It emphasises and promotes data independence; proper use of keys; extensibility; quality; and ease of use, and produces a genuinely Relational database....more
SPEM Activity diagrams
OMG Software Process Engineering Metamodel Stencils for Omnigraffle. Using SPEM you can plan or inspect the engineering approach in software projects. You can use it to learn from previous approaches as well as to simply improve the processes in your company.
Feature Diagrams
Feature Diagram stencil, notation based on the book "Generative Programming" by K. Czarnecki and U.W. Eisenecker. Updated, version 2 improves quality (circles do no longer overlap connected boxes).
UML 2.1 Collection
A collection of notation elements for creating UML 2 class, activity, use case, sequence, or component diagrams. It's a rather large stencil, but it contains most UML 2.1 elements. A tool converting Eclipse Java packages to UML class diagrams using this collection can be found on the linked website. Version history: 1.11 (Jun...more
