[NC-Verilog] ncelab: *F,CUMSTS: Timescale directive missing on one or more modules. 錯誤訊息的原因
這是因為有些 Verilog module 並沒有指定 timescale. 可以在 ncelab 指令中加入 -timescale 1ns/10ps 來指定預設的timescale, 或是在所有 Verilog module 前都指定 timescale.

ncvlog: *E,UNBERR: (1) unbound instance(s). 的解決方法
在run ncvlog simulation時出現以下錯誤訊息:
ncvlog: *W,UNBINS: Unbound instance found: OOOXXXYYYZZZ
ncvlog: *E,UNBERR: (1) unbound instance(s).
其實是在gen netlist時將某些路徑設錯了 (但gen netlist時沒有錯誤訊息, 而是run simulation時才出現),
