To know how to make a subcircuit, refer to \chapref{chap8}. \subsubsection {NGHDL} -NGHDL is an add on to eSim for mixed mode circuit simulation. By using the foreign language interface of GHDL, NGHDL communicates with Ngspice and accomplishes mixed-mode simulation. Using NGHDL, user can create custom digital model using VHDL language. From simple multiplexers, counters to microcontrollers and ASICs, any custom component in the digital domain can be realized using the NGHDL tool. The created digital model can be used in either mixed-mode circuit or a standalone circuit operating in digital domain. NGHDL gives user the liberty to edit existing models supplied with eSim per their needs, either for experimenting new ideas or to change the model per their specific requirement. +NGHDL is an add on to eSim for mixed signal circuit simulation.
