Playing around spinal in scala console fails about spinalhdl HOT 6 OPEN

Hi,

SpinalHDL can't realy be used in console mode in this way. You have to provide a toplevel component :

SpinalVerilog(new MyTopLevel)

And have all your hardware statements in that toplevel herarchy

Reason is that SpinalHDL has a lot of hidden stuff happening under the hood which require some setup (done by the SpinalVerilog function)

FYI in case the sbt startup time is annoying you and that's the reason why you want to use the REPL: you can just start sbt once and repeatedly run runMain, etc. in there - that makes it much quicker to use. (sorry in case you already knew)

Thanks for pointing out this. Personally I prefer the console way (works like python console which I use a lot). Though '~runMain' produces immediate results, it runs the whole code and print everything all at once.

With console, it seems to be more newbie-friendly. For example, to find out the difference between 'd := a |<< c' and 'd := a << c', I can put them in console and see the difference.

Go it. Assume I'd like to learn the difference of '##' and '@@', as a newbie, the preferable way to do so is to type the following code (Pardon me if it has errors):

val a = U"8'h5"
val b = U"8'hA"
println( a @@ b )
println( a ## b)

Is there a way?

Personnaly, i'm using Intellij Idea and that template project :
https://github.com/SpinalHDL/SpinalTemplateSbt

Else you can use sbt to generate some verilog, see the readme of that template project.

Else you can do some one liner as :
SpinalVerilog(new Component{val a = U"8'h5"; val b = U"8'hA"}).printRtl()

But the thing is that you need your repl to have the SpinalHDL compiler plugin in. i never tried.

OK, i'll figure it out. Thank you Dolu.
