Old Game Development IDE Goes FPGA

2018年12月24日 | By News | Filed in: News.


If you have a thing for old game development — things like the Atari 2600 or similar period arcade games — you might already know about the 8bitworkshop IDE. There you can develop code in your browser for those platforms. In a recent blog post, the site announced you can now also do FPGA development in the IDE.

According to the site:

Most computers are fast enough to render a game at 60 Hz, which requires simulating Verilog at almost 5 million ticks per second.

To activate Verilog, you need to select the hamburger menu to the top left, select Platform, and then under Hardware, check Verilog. What makes this different from, say, EDA Playground, is that the output can be waveforms or the output to a virtual TV monitor. For example, here’s one of the examples:

The Verilog code is generating horizontal and vertical sync along with an RGB output and the results appear on the monitor to the right. There is a handle at the bottom of the screen. If you drag it up you will see the logic analyzer output. Drag it down and you’ll see the screen again. The examples include an 8-bit and 16-bit CPU, and example games that can even read the mouse.

Honestly, we don’t think anyone would suggest using Verilog to write in-browser games. That isn’t really the point here. However, if you are trying to learn Verilog, it is great fun to be able to produce something other than just abstract waveforms from simulation. The only downside is that to move to a real piece of hardware, you’d need to duplicate the interfaces provided by the IDE. That would not be very hard, and — of course — if you are just using it to learn you can try a different project for the real world.

If you need help getting going in Verilog, we have a series of boot camps that can help. Those tutorials use EDA Playground, but they’d probably work here, too. If you try them in the IDE, be sure to let us know your experience.
