Define SPEC || |:---:| |更改Instance Name| |定義記憶體深度(word)| |定義記憶體的寬度(bit)| |定義多工器的寬度,不同的寬度可以設定不同的記憶體深度與寬度| |最後按update| |Example:(Words = 8, Bits = 16)| |:---:| || > 65536超過bit限制則視為0 2. Output File  3. Writing Spec(方便tool往後對於記憶體規格的查照)  Appendix --- 由於Memory Compiler只輸出.lib檔,因此若要使用Design Compiler等工具則必須將.lib轉檔 利用 lc compiler 1. #> lc_shell 2. #> read_lib library_name 3. #> write_lib -format db USERLIB -output xxx.db
