PICsim Alternatives
PICsim is described as 'emulates a microcontroller PIC16F628/16F777/16F877A/18F452/18F4550/18F4620 and periferics such as USART and timers, the simulator architecture permit easy implementation of external elements in c language' and is an app. There are five alternatives to PICsim for Linux and Windows. The best alternative is Virtual Breadboard, which is free. Other great apps like PICsim are proteus VSM, SimulAVR, simavr and Emulino.
PICsim alternatives are mainly Circuit Simulators but may also be Electronic Design Automation Tools. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of PICsim.It is a circuit simulator on a virtual breadboard. it supports virtual components like microcontrollers, TTL, graphical and alphanumerical LCDs and others in addition to virtual instruments and certainly the basic components (resistors, capacitors..).
A virtual simulation environment for electronic circuits with support of digital and analog devices. It also provides virtual instruments and virtual debugging tools.
