本文主要是介绍记录OCEAN报错信息和对应解决方案，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
- 记录OCEAN代码报错信息和对应我代码部分解决方案
Error fprintf/sprintf: format spec. incompatible with data - “Format is ‘GBW IS %e\n’, argument #1 is nil” - 使用gainBwProd()测得GBW返回值为nil，导致printf出错
- 添加检测代码
if(GBW == nil printf("GBW IS %s\n", "NAN"))
Error putprop: first arg must be either symbol, list, defstruct or user type - nil - 使用gainBwProd()测得GBW返回值为nil，导致fprintf写文件出错，检测是否有变量值为nil
https://community.cadence.com/cadence_technology_forums/f/custom-ic-skill/24357/strange-error-putprop，cadence论坛也提到是因为有个数为nil
I finally found out that the problem was in one of the expressions and it was not being evaluated and causing an error since it was performing some operation on a nil. 我写在了procedure里，所以无法定位是哪句报错了
这篇关于记录OCEAN报错信息和对应解决方案的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
