Detailed Description​

class chronon::observe::Counter;

Counter - Internal per-instance counter storage used by EventCounter and DerivedCounter.

Each unit instance has its own counter with separate values:

  • Counter names include the unit's hierarchical path (e.g., "cpu0.alu0.ops")
  • Fast increment path (~2-3ns) via direct context access

Output (CSV):

cycle,unit_name,counter_name,value
10000,cpu0.alu0,ops,2500
10000,cpu0.alu1,ops,2400
10000,cpu1.alu0,ops,2550
