abstract class BlackBox extends Component
A blackbox allows the user to integrate an existing VHDL/Verilog component into the design by just specifying the interfaces.
class Ram_1w_1r(wordWidth: Int, wordCount: Int) extends BlackBox { val generic = new Generic { val wordCount = Ram_1w_1r.this.wordCount val wordWidth = Ram_1w_1r.this.wordWidth } val io = new Bundle { val clk = in Bool() val wr = new Bundle { val en = in Bool() val addr = in UInt (log2Up(wordCount) bit) val data = in Bits (wordWidth bit) } val rd = new Bundle { val en = in Bool() val addr = in UInt (log2Up(wordCount) bit) val data = out Bits (wordWidth bit) } } mapClockDomain(clock=io.clk) }
