brave_opt is a Tcl script compatible with Shy_HLS, aimed at minimizing power
and area under latency constraints.
The basic idea behind brave_opt is:
- filter out non-convenient functional units
- bind all nodes to fastest functional units (in order to check if the scheduling is feasible)
- slow down every node as far as timing constraints are satisfied
- schedule nodes using a Minimum Area Latency Constrained algorithm
N.B. "non-convenient functional units" are:
- slower and more power consuming
- slower, equally power consuming and more or equal area requiring
This filtering is hence prioritizing power saving: this choice has been taken considering that in modern designs power consumption is usually more critical than area occupation.
