This is the top level module, that imports -> import_chisel_mod which imports -> ToImport. This collection of notebooks and .sc files are meant to demonstrate how to do chisel development in a notebook environment, particularly how to import the modules implemented in one notebook to another.

Lets use this imported module to build a module in this notebook:

DoubleComposedMod (GitHub)

DoubleComposedMod[source]

defined class DoubleComposedMod

test(new DoubleComposedMod) { c => 
    c.io.in.poke(1.U)    
    c.clock.step(1)    
    c.io.out.expect(7.U)
    
    c.io.in.poke(5.U)    
    c.clock.step(1)    
    c.io.out.expect(11.U)
}
