it looks like that simavr does not recognize/accept a vcd input file OR the layout/structure of the vcd input file is not well documented. I try to stimulate PB2 as...

Hi, I'd like to be able to simulate an Attiny4/5/9/10 for a project, but this core is not currently supported by simavr (or any other FOSS simulator). A [datasheet](http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8127-AVR-8-bit-Microcontroller-ATtiny4-ATtiny5-ATtiny9-ATtiny10_Datasheet.pdf) is...

This allows to simulate a 'real' signal time patterns on SPI interface related MCU pins and communicate with diverse devices over it. Should also fix #222.
