Change was on the way: Minicomputers and later personal computers came on the scene with new operating systems, which made all the hocus-pocus associated with using large scientific programs on the old mainframes, obsolete. Virtual memory replaced overlays. New graduates, no longer intimidated by the computer, were more than capable of dealing with any programming situation. Today, the technical expert has control over both the computer and its programs and is intimately involved in adapting both hardware and software to meet his/her requirements for investigation and analysis.
EMTDC was developed for this new and more acceptable environment, first specifically for UNIX/Linux, and then on to Microsoft Windows operating systems. Model building of control and electric systems is no longer defined entirely by data entry – with the program hidden, untouchable somewhere in the depths of the computer memory: Now the model is created by user Fortran statements. Time domain model components, such as AC machines, exciters, six-pulse valve groups, etc., are modularized into subroutines for easy assembly by the user. The user is able to build his or her subroutines, if and when models are not available.
With the advent of PSCAD, the graphical user interface for EMTDC, there is for the most part, no longer any need for the user to build his/her own subroutines through coding. Subroutine assembly and insertion into EMTDC is now performed automatically by PSCAD. The responsibility of the user has been reduced to graphically assembling a given network, and in some cases, adding some user-defined code. However, there may still be a need in some instances, such as the conversion of older subroutines, where a good knowledge of the internal structure and methods of EMTDC is important.

Preparation and testing time is reduced due to the PSCAD Graphical User Interface.
In EMTDC, many series and parallel electric elements are mathematically collapsed (such as an RLC branch) to reduce the amount of nodes and branches.
The Optimal Ordering algorithm in EMTDC serves to increase LDU matrix decomposition speed.
The Optimal Switch Ordering algorithm ensures that switching operations are very fast and efficient by moving switching elements to optimal conductance matrix positions.
EMTDC utilizes subsystems, which takes advantage of the fact that the numerical solution of electric networks, separated by travelling wave transmission lines, are mathematically independent.
An Interpolation algorithm is used in EMTDC to perform switching operations. This allows any switching event to occur at the exact switching instant, even if this instant is between time steps. This allows EMTDC to run at a larger time step (faster), yet maintain accurate results. Also, additional snubber circuits are not needed to address inherent numerical troubles.
