Calculation method
Calculation method
Bounded call-chain stack estimate (bytes)
Longest weighted acyclic call path; function weight=frame×declared recursion bound; add interrupt reserve.
Per-function path estimates
Longest downstream weighted call chain from each function.
Symbols and units
- a
- Functions [ID,frame bytes,maximum recursive frames]
- b
- Acyclic inter-function call edges [caller,callee]

- Additional interrupt-reserve bytes
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Call graph, frame sizes, recursion bounds. Returns Bounded maximum stack estimate. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Additional interrupt-reserve bytes: minimum 0, maximum 100000000.
