Now the simulator is free in Vivado but I still don't use it. As a result, I have never used the simulator. The IDE was free, the synthesis and place/route tools were free but not the simulator. In earlier times with Xilinx ISE, the simulator wasn't free.

The other parts are knowing your way around the development tools, knowing how to properly simulate things, understanding timing closure, understanding the limitations and advantages of specific FPGA families, learning how to efficiently use the FPGA resources and in general a lot of computer science stuff in how to efficiently do various tasks in the digital world. Actually learning how to implement a large project and getting it to compile and run on a real FPGA is much harder as knowing a HDL language is only a small part of it.

Yes the actual HDL code is universal and portable, but real world projects with FPGAs always use some of the chip specific hardware because it makes for huge performance gains(memory blocks, hardware multiplier blocks, serdes blocks, memory controllers etc) You can learn a HDL language really well in 1 week if you put yourself to it. The majority of HDL code you find in the real world is very vendor specific and will not port easily to any other compiler/IDE. FPGAs are not like C where the same piece of code easily recompiles for any architecture that a C compiler exists for. But they do have precompiled binary blobs of there modules for the specific simulator they support and the simulator is aware of them so it just magically works. The manufacturers don't give out models for the on chip functionality in plain HDL source code so you can't just stick the code into any simulator out there. Main reason is that as soon as you use any chip specific functionality (Even as simple as memory blocks) you will need a simulation model for that block to be able to simulate a design that uses it. Education has never been free and it won't be for FPGAs either.īest simulators tend to be the ones included with your FPGA tools. Digilent has some gadgets that help with this but there is no way that Arty will ever be the board the Nexys board is. Either that or I have to gin up some kind of display/switches/pushbutton arrangement and hang it off the edge. A very common board might be something like the Arty I have a couple of them and they are very useful but in many ways it's like working in the dark. I can also use a pushbutton for single-stepping. I know it is over the top in price but I really like this type of board: I can get a lot of diagnostic information from the LEDs and displays and I can select what I see with the switches. OTOH, in the Digilent world, there are a lot of interesting gadgets that connect to the PMOD headers. I also want as many offboard connections as possible and I prefer with 50 pin headers over the 6 or 12 pin PMOD connections. I like lots of switches, LEDs, buttons and 7-segment displays. When you look at boards to buy, you need to consider what is on the board.
