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.

The first lines of code were written in 1975, at Manitoba Hydro by Dennis Woodford (Technical Director of the Centre 1986 - 2001), out of a need for a simulation tool that was sufficiently powerful and flexible to study the Nelson River HVDC power system in Manitoba, Canada.
Following the success of this study, development of the program continued through the next two decades. Over this time, a full spectrum of professionally developed models was eventually accumulated (as needed for various simulation projects) - in addition to various enhancements to the actual solution engine itself.
