Suggestion to Change the Schematic Symbol of Digital Components

QUCS can be downloaded at: https://sourceforge.net/projects/qucs/

Components

QUCS circuit simulator has an ability to work with analog and digital components. That is why I am using it not only for its free to use, but, also this software can integrate analog with digital components. Of course, many simulation software offers more and perform better than QUCS. For the fact that it is free to download and use, we can not under estimate this software.

There is a thing or section in digital component that bothers me. Some digital components have wrong schematic symbols. For some people they find it okay because it is just a symbol and it do not alter that function of the component. But for me, as a professional in the field of electronics I know the value of schematic symbols. It gives identity from component which is unique and no other components have the same symbol with others.

For me, schematic symbols are language use in electronics. With the schematic diagram using symbols, users can understand the function of the circuit and what components need to be used.

These schematic symbols must follow the international standards so that users all over the world can understand and to avoid confusions. So, suggested to enhance or change the schematic symbols for some digital components.

Proposal

The digital components which I believe have wrong schematic symbols are logic gates. They are the inverter, buffer, and gates, or gate, and more. The Integrated circuit (IC) symbols are ok because IC can be varied in symbols as long as they have rectangular in shape and with pins.

What I am proposing here is to change schematic symbols of logic gates in QUCS digital components.

These are the current symbols used for logic gates in QUCS.

Here are the ANSI and IEC standard symbols for logic gates. ANSI stands for American National Standards Institute and IEC stands for International Electrotechnical Commission these are agencies assign to standardized symbols.

From the symbols given by ANSI and IEC, some symbols used in QUCS are not there. These are inverter, OR gate, NOR gate, NAND gate, XOR gate, XNOR gate, and buffer. Therefore, these symbols must be change to follow the international standards for symbols.

Mockups / Examples

Here are the examples on how to implement this suggestion.

The current symbols stated will be changed.

Digital component library will have a new look like this.

Benefits

Here are the benefits if implemented:

1. QUCS logic gates will now follow the international standards for the schematic symbols.
2. Users will not be confuse with the schematic symbols because it is the same to some software and reference books.
3. Users all over the world can communicate well using the standard symbols.
