Refuse a design whose expanded graph will not fit in memory, before any of it is built.

How many SimulationComponents the merged graph will hold.

What the expanded design will cost in heap, by the same reckoning checkExpansionFits refuses on. Costs a walk of each sheet's canvas and never of the expansion, so it is cheap enough to ask before every simulation - which the waveform simulator does, to decide how many clock cycles to start with rather than only whether to start at all.

How many SimulationComponents the merged graph will hold, and how many ports they have between them - which is what says what they will cost.

 Try to resolve all the dependencies in a graph, and replace the reducer
 of the custom components with a simulationgraph.
 

 Merges dependencies into the simulation graph and resolves all parameters.
 
 The name of the current sheet being processed
 The initial simulation graph to merge dependencies into
 The current canvas state
 List of all loaded component sheets
 
 Success: A fully merged and parameterized simulation graph

 Parameter Resolution:

 Stage 1 - Merging (via merger function):
 - Custom components are replaced with their internal graphs
 - Parameter resolution is DEFERRED to avoid forward reference issues
 - Each custom component's graph is stored in CustomSimulationGraph field

 Stage 2 - Parameter Resolution (resolveParametersInSimulationGraph, after all merging):
 - The top sheet is resolved with its own default bindings
 - Each sheet below is resolved with the bindings of the instance containing it, so instance
   bindings override defaults
 - Sheets whose bindings give the same difference from their defaults are resolved once

 

Resolve every parameterised slot in a sheet and, recursively, in the sheets of the custom components it contains. `state` is unused: the slots come from the LoadedComponent.
