Dev Diary: ACDC on the Horizon

In many countries, the Covid outbreak has caused many setbacks in industries around the world. With the restrictions in movement and the slowing down of the economy, many due dates or releases of new products would have to be delayed. In FILPAL, we face similar challenge with the Movement Restriction Order (MCO) in place. However, that does not mean there is no progress being made. Today let me give a sneak peak into what we had been working on in the pass few months. Take note that all images shown here are work in progress and not finalized.


Introducing FILPAL EDS ACDC. Where FILPAL EDS HF is designed to process High Frequency designs, FILPAL EDS ACDC, as the name implies, is used to perform many AC and DC related simulations.

So, what can we expect from this software? Here are a few features you can expect from the upcoming EDS ACDC software.

1. Various Analyses Options

EDS ACDC consist of many types of simulations and analyses. To name a few, they are AC analysis, DC simulation, DC Operating Point, AC Noise Analysis, Transient Analysis and many more. We are also attempting to upgrade the chart plotting as compared to EDS HF, making the chart UI to be more modern. Due to ACDC simulations usually requiring more parameter inputs when compared to HF, we will be attempting to make the settings to be as simple and easy to use as possible.

2. Straightforward Schematic

For many who are familiar with ACDC related EDA tools, you will surely notice that sometimes the schematic not as direct as it seems. For example, usually in textbooks, dependency sources are usually portrayed as a 2 port. However due to the nature of dependency sources, in many EDA tools, they are portrayed as 4 port network to facilitate its function. In EDS ACDC, we strive to make all the schematic to be as close to the textbook examples as possible. We believe by doing so, it helps students to actually relate better and makes it easier for them to translate what they learn in textbook into workable examples in E-learning.

3. SPICE Modelling

SPICE is an open source circuit simulation program when it was first developed. Currently, most software are able to process SPICE Models as it has become a general-purpose circuit simulation model. EDS ACDC will incorporate the ability to read SPICE models and even generate them based on the schematic constructed.

4. Intuitive Interface

Due to the amount of parameters that are usually involved in ACDC type simulations, it can be very overwhelming for initial users to be able to work efficiently using ACDC EDA tools. For EDS ACDC, we will be constantly refining our interface to make it as intuitive and simple to use for users as possible.

And that’s all for now. We hope to be able to bring this software to release by end of year 2020. Until then, stay safe and healthy while the world weather the Covid storm!
