Figure 1. Workflow in GeNN. The “user-side” code is shown in boxes with green titles, and the files that are controlled by GeNN are shown in boxes with red titles.

Code in red in the user program indicates the functions that are part of the code generated by GeNN. Simulating a neuronal network in GeNN starts with a modelDefinition() (top) which feeds into both, the meta-compiler generateAll.cc (1, middle left) and the “user-side” simulation code (4, right). The meta-compiler generates a source code library (2, bottom left) which can then be used in “user-side” simulation code (3, bottom right).
