无法在 Chisel3 中使用 PeekPokeTester 进行打印
Can't printf with PeekPokeTester in Chisel3
在使用此测试平台代码测试我的 chisel3 设计时，我试图打印一些值：
package taptempo
import chisel3._
import chisel3.iotesters
import chisel3.iotesters.{ChiselFlatSpec, Driver, PeekPokeTester}
import scala.language.reflectiveCalls
class TapTempoUnitTester(t: TapTempo) extends PeekPokeTester(t) {
val tptmp = t
printf("Begin of test\n")
def pushbutton(button: Bool) {
poke(button, 0)
step(1)
print("Push \n")
poke(button, 1)
step(10)
poke(button, 0)
}
val tclk = tptmp.tclk_ns //ns
val tms = 10*tclk
val ts = 1000*tms
for(i <- 0 to 6) {
peek(tptmp.io.button)
pushbutton(tptmp.io.button)
step(1*tms)
}
printf("End of Test\n")
}
class TapTempoTester extends ChiselFlatSpec {
behavior of "TapTempoTester"
it should "launch a simple test" in {
chisel3.iotesters.Driver(() => new TapTempo(100000)) {
c => new TapTempoUnitTester(c)
} should be(true)
}
}
但是我在使用命令启动测试台时遇到了这个错误：
sbt 'test:runMain taptempo.TapTempoMain'
错误：

如果我删除 'printf' 行，则测试台可以正常工作。
是否可以使用 chisel3 iotester 在 testbench 中打印一些文本和值？
完整项目源自凿子模板 github，可在我的 github 存储库 TapTempoChisel.
中找到
好的，终于找到问题了。这是一个 导入 问题。在源文件的头部有一个 :
import chisel3._
听起来和printf有冲突。我需要这个导入 Bool，然后如果我们直接导入 Bool :
import chisel3.Bool
并删除 chisel3._ 导入，效果很好。
如果不想放弃方便的chisel3._导入：
System.out.printf("haha, this works\n")
通过这种方式，它直接调用 Java System.out.printf 函数，从而绕过了失败的 printf 的 Chisel-overridden 版本。
在使用此测试平台代码测试我的 chisel3 设计时，我试图打印一些值：
package taptempo
import chisel3._
import chisel3.iotesters
import chisel3.iotesters.{ChiselFlatSpec, Driver, PeekPokeTester}

val tptmp = t
printf("Begin of test\n")
def pushbutton(button: Bool) {
poke(button, 0)
step(1)
print("Push \n")
poke(button, 1)
step(10)
poke(button, 0)
}
val tclk = tptmp.tclk_ns //ns
val tms = 10*tclk
val ts = 1000*tms
for(i <- 0 to 6) {
peek(tptmp.io.button)

}
printf("End of Test\n")
}
class TapTempoTester extends ChiselFlatSpec {

it should "launch a simple test" in {
chisel3.iotesters.Driver(() => new TapTempo(100000)) {
