Visitor that solves ODEs using old solvers of NEURON More...

Detailed Description

Visitor that solves ODEs using old solvers of NEURON

This pass solves ODEs in derivative block using cnexp, euler and derivimplicitmethod. This solved mimics original implementation in nocmodl/mod2c. The original ODEs get replaced with the solution and transformations are performed at AST level.
