除了testwaitfortimeout（）外，CAPL中的延迟函数

问题描述

我有一个控制GPIB电源的CAPL测试节点。该CAPL生成一个每3 ms修改一次的信号。我的CAPL看起来像这样：

I have a CAPL test node that controls a GPIB power supply. This CAPL generates a signal that is modified each 3 ms. My CAPL looks like this:

...
testcase wavGenerator()
{
   GPIBWrite(myDevice, "VOLT", voltValue);
   testwaitfortimeout(3);
   ...
}

问题是此testwaitfortimeout（）函数会在测试报告中生成注释，并且由于我为每个测试用例使用此功能2000/3000次，因此我得出了巨大的测试报告。

The problem is that this testwaitfortimeout() function generates a comment in the test report, and since i use this function 2000/3000 times for each testcase, I end with a enormous test report.

我尝试实现一个函数来生成延迟，就像waitfortimeout（）一样，

I have tried implementing a function to generate a "delay" like waitfortimeout() does, like this:

void delay(int ms)
{
   float refTime;
   refTime = timeNowFloat();
   while(timeNowFloat() < (refTime + ms*100))
   {
      /* Wait to reach expected time*/
   }
}

但这会使CANoe崩溃。我已经使用setTimer（）函数尝试过类似的操作，但是问题是相同的。我怎么能产生这种延迟？

but this crashes CANoe. I have tried something like this with setTimer() functions but the problem is the same. How can I generate this delay?

推荐答案

我找到了一种使用计时器，EnvVar和函数来处理此延迟的方法。 testWaitForEnvVar（）

I found a way to deal with this, using a timer, an EnvVar and the function testWaitForEnvVar()

on timer tDelay
{
  @EnvDelayFunct = 1;
}

void delay(int ms)
{
  int a;
  write("Wait for %i ms", ms);
  setTimer(tDelay, ms);
  a = testWaitForEnvVar(EnvDelayFunct, 0);
  @EnvDelayFunct = 0;
}
