【问题描述】:
当我尝试使用 Vivado HLS 进行合成时,我收到关于不可合成类型的错误。我的项目是关于霍夫曼编码的。
@I [HLS-10] Starting code transformations ...
@I [HLS-10] Checking synthesizability ...
@E [SYNCHK-11] huff.c:17: Constant 'temp' has an unsynthesizable type '[13 x %struct.tnode.0.2.4]*' (possible cause(s): structure variable cannot be decomposed due to unsupported type conversion or memory copy operation).
@E [SYNCHK-11] huff.c:21: Constant 'ptemp' has an unsynthesizable type '[13 x %struct.tnode.0.2.4*]*' (possible cause(s): pointer to pointer or global pointer).
@E [SYNCHK-72] huff.c:24: unsupported c/c++ library function 'qsort'.
@E [SYNCHK-41] huff.c:38: unsupported pointer reinterpretation from type '%struct.tnode.0.2.4 = type { %struct.tnode.0.2.4*, %struct.t...' to type 'i8*' on variable 'ptemp'.
@E [SYNCHK-42] huff.c:47: pointer comparison is not supported.
@I [SYNCHK-10] 5 error(s), 0 warning(s).
@E [HLS-70] Synthesizability check failed.
在做C sim的时候也有一些困难。

附件包括我的“顶级功能”的代码。 我没有使用 HLS 工具的经验。有人可以帮我解决这个问题吗?我们如何在 vivado HLS 的顶级函数中包含数据结构? 谢谢你

如果您在导致问题的问题中放置一个简短的示例代码,并且可能专注于一个问题,这将很有帮助。
