Ah i think you are trying to use the isZero opcode which we have not implemented. Is it possible to comment that check out ?

This panic comes from:

https://github.com/appliedzkp/zkevm-circuits/blob/f3a6020ab5a0b1e04acf15155390b0d2786f3a87/zkevm-circuits/src/evm_circuit/witness.rs#L1035

For workaround, we can use ExecutionState::STOP which is only a placeholder now as fallback, to make trace with unimplemented opcodes work.

-            _ => unimplemented!("unimplemented opcode {:?}", step.op),
+            _ => {
+                println!("unimplemented opcode {:?}", step.op); // TODO: use log::warn
+                ExecutionState::STOP
+            }

We are working on IsZero already. Will submit PR soon.

@lispc are yall planning to reuse eq opcode to reduce duplication ?

For example this is the same as == 0 so can juts reuse the opocde with a constant.

ISZERO is now at #399.

Currently EQ, LT & GT are combined in ComparatorGadget.

Skimming it over, I think adding ISZERO into it may not reduce duplication or either improve readability.

@pinkiebell ISZERO spec and circuit are all merged recently.
