如何編寫一個生成文件，其中編譯後的目標文件位於具有不同名稱的不同目錄中？

Question

所以我試圖寫一個Makefile以與QuestaSim和systemverilog文件一起使用。如果你不知道那是什麼（而大多數人不會），那麼別擔心，這與我的問題沒有關係。

我有一個包含項目總監：SRC /工作/ Makefile中

src /目錄中包含幾個目錄，每個包含的源文件。

工作/目錄不存在最初，由生成文件創建。

當我把我的「編譯」這就是所謂的VLOG，在目錄上獲取的工作文件夾具有相同的名稱作爲不帶後綴的.sv文件中創建一個.sv文件。在那個目錄中有三個文件，我將用作我的「對象」文件的文件是_primary.dat。

例如，調用「vlog src/interface/my_interface.sv」創建（如果成功） /my_interface/_primary.dat

我.sv文件還需要按照特定的順序進行編譯，而我只想編譯它們如果源文件或他們的依賴的一個改變。

我可以把使用「$（addsuffix /_primary.dat，$（addprefix $（VLIB_DIR）/，$（basename $（notdir $（SRC）））））將.sv文件的路徑導入到相關_primary.dat文件的路徑中。 「但是相反的情況是不可能的，因爲我們沒有目錄結構。」

所以我想我想要的是某種來自object - > src的映射。因此，在我的$（OBJ）目標中，我可以執行「vlog $（getsrc $ @）」。

之後，我必須處理編譯順序和依賴關係，但我大概可以工作了這一點。

有什麼建議嗎？

我發現了一個可行的解決方案。我不確定它是最好的，但我會在這裏發佈它來幫助有這個問題的其他人。

基本上，我創建了一個宏以兩個參數：.sv源文件路徑和名稱，以及依賴列表。這將源文件路徑轉換爲目標文件路徑並將其創建爲目標。依賴於源文件和任何依賴關係。然後我創建一個包含我所有源的列表的變量。最後我做：$（foreach src，$（SRCS），$（eval $（call create_target_for，$（src）））），它創建了我所有的目標。

此外，我有每個子目錄作爲一個僞目標，與相關的依賴關係，讓我得到目錄正確的編譯順序。

唯一缺少的是，如果我需要確保在一個單一的目錄中的文件有正確的編譯順序。

我的Makefile：

# Makefile for use in building all my UVM components 
# ---------------------------------------------------------------------------------- 
# Requirements: 
# QuestaSim - We use the vlog compiler packaged with QuestaSim. 
#  ModelSim also comes with vlog, but doesn't really support UVM. 
# UVM_INCLUDE_DIR environment var - This should point to the UVM src directory. 
#  For me this is: C:\questasim_10.0b\verilog_src\uvm-1.0p1\src 
# ---------------------------------------------------------------------------------- 
# Notes: 
# The vlog compiler creates an output folder in the VLIB_DIR directors 
# per package/module/interface with the same name as the entity 
# Any capitals are replace with @ followed by the lower case letter 
# IE. FooBar -> @foo@bar 
# This makefile requires that: 
#  All interfaces end in _if 
#  All packages end in _pkg 
#  Each file can only contain a single interface, package or module 
#  No capitals in package/module/interface naems 
#  The package/module/interface has the same name as the file 

# some variabls to use later
