The Spatial Compiler¶
Compilation¶
The Spatial Compiler is run using:
bin/spatial <Application Name> [flags]
where <Application Name> is the name of the Spatial application object.
Compiler Flags¶
The following compiler flags are available in the Spatial compiler:
| –sim | Turns on the Scala backend for functional simulation. |
| –synth | Turns on the Chisel RTL backend for cycle-accurate simulation and/or synthesis. |
| –instrument | Enables RTL instrumentation hooks for manual pipeline balancing analyses |
| –retime | Enables RTL retiming to meet higher clock speeds. |
| This flag will eventually be enabled by default. | |
| –syncMem | Enables synchronous memory operations for all SRAMs to use fewer resources. Also enables –retime. |
| –out <dir> | Specifies an output directory to place generated code. Default directory is gen/<app name>. |
Advanced Compiler Flags¶
These flags are primarily for use in development of the Spatial compiler.
| –cheapFifos | Uses “cheap” FIFOs if there are no FIFOs with lane-dependent enqueues or dequeues. |
| –multifile | 0-6, default = 4 |
| –naming | Turns on useful naming for assistance in debugging generated chisel |
| –dse | Run compiler design space exploration. Interactivity is planned, but currently just generates a data file. |
