Chisel/FIRRTL: Chisel Data Types
WebChisel Data Types. Chisel datatypes are used to specify the type of values held in state elements or flowing on wires. While hardware designs ultimately operate on vectors of binary digits, other more abstract representations for values allow clearer specifications and help the tools generate more optimal circuits. WebChisel supports a global clock and reset Basic := and Register operators update are positive edge-triggered Can use this to create useful counters and pulse generators def counter(max: UInt) = {val x = Reg(init = 0.U(max.getWidth.W)) x := Mux(x === max, 0.U, x + 1.U) x} // Produce pulse every n cycles. northeast mn real estate
Chisel/FIRRTL: Experimental Features
WebChisel is the project at the origin of Spinal and Chisel it represents a big step forward compared to common HDL. However, it has several drawbacks for large designs that mix multiple clock domain and external IP (black-boxes). In fact, Chisel show some serious conception issue : Multiple clock support is awkward: WebApr 17, 2014 · to chisel-users Update. This appears to work. class MemoryController extends Module { val io = IO(new Bundle { val ddr3 = Output(new DDR3Command()) }) val resetDDR3Cmd = Wire(new DDR3Command())... WebJun 23, 2024 · Currently the verilog code generated from chisel3.3 is able to do async reset on posedge. But the backend team requires negedge reset due to foundry technology. The answer 2 to this post generates a reversed resetn signal, but still with posedge. Is there a switch to set so that the generated verilog can be like this? northeast mn map
