Various Procedures and Challenges while working with ESIM.

First the ESIM software needs to be installed as well as the ngspice software and the SKYPDK folder.
Proper research of the circuit and its importance needs to be there
Implementation of the circuit and subcircuit needs to be implemented in ESIM.
Then the SKYPDK130nm mos needs to be inserted inside the .cir file and kept in the same folder as the SKYPDK FOLDER.
The SKYPDK lib file needs to be included in the .cir file as well.  

WATCH THE DAC IP course from UDEMY by KUNAL GHOSH.

While creating the circuit there were few handling difficulties of the software but the IP DAC course helped a lot in the same. Understanding the whole software as a whole was a little bit complex, took some time to get used to it .Maybe using Cadence and Ltspice was the reason of the same.
There were few warnings which were shown in the software which I could not understand. The same circuit implemented in other softwares did not show such warnings. Next is the component part few of the components were present in the component list but due to lack of spice code inavaibility couldn’t implement the same as the transformer and the LM7805. Need to put alternative methods for the simulation and the completion.

FEEDBACK

Overall a nice experience but still a huge area of improvement needs to be there as Ngspice usage and ESim usage is a little difficult and inappropriate for the industry at the moment with CADENCE and Ltspice already in picture and Ltspice is a free software as well. The component library needs to be improved and proper explanation of errors needs to be there.
