SysML (visit SysML 1.2 at http://graffletopia.com/stencils/849) parametrics is based in part on a theory called composable objects (COBs). Composable objects have been developed at the Georgia Institute of Technology (GIT) as a means for representing and integrating design models with diverse analysis models. Design and...more
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
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
DEMO is an acronym for 'Design & Engineering Methodology for Organizations'. The name also stands for the demonstration that the underlying PSI-theory (Performance in Social Interaction) is a viable basis for practically dealing with organizational changes of all kinds.
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
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
Contains all the major components for a Functional Flow Block Diagram (FFBD), which are used in developing the functional architecture of a system and describing the system's functional flow.
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
