為了測試由FPGA實現的四相單軌握手協議電路的性能，通過狀態機設計無冒險的計數器作為GALS系統兩端的同步電路，采用Altera公司CycloneⅡEP2C35F6-
72C6器件作為測試器件，通過邏輯鎖定技術將標準C單元模塊添加進設計中，通過建立wport、rport的父區域（Parent Region）鎖定模塊，將子區域（Child Region）鎖定的C單元添加進父區域鎖定模塊，保證了各自時序的獨立性，確保了電路功能的實現。其時序仿真結果如圖5所示。
對結果進行分析：當全局復位信號為高電平時，對全局電路進行復位。整個握手實現過程通過同步模塊的2個計數器在進位時，輸出各自的進位信號作為wr和rd信號，當二者同時為高電平時發生握手，且作為接口電路rport、wport的輸入信號。當req上升沿到來時，ack響應req信號變為高；
當req下降沿到來時，ack拉低。通過ack的上升沿觸發鎖存器傳遞數據，完成數據的通信，其數據主要是由計數器產生的0、1信號。而對于時鐘暫停模塊，當str1、str2信號為高電平時分別對兩個模塊的時鐘進行暫停，從仿真圖中可見，當兩者為高電平時，將時鐘置為0，保證了時鐘的可暫停。
整個系統通過設計的C單元庫，實現了GALS中的接口模塊、時鐘暫停模塊，達到GALS系統同步模塊間異步互聯的效果，且使用的是四相單軌握手協議，具有較好的握手性能。使用Quartus軟件的邏輯鎖定技術，對子區域（C單元）、父區域（接口電路）進行鎖定，確保了C單元在與整個電路綜合中不出現冒險問題，確保了電路的可行性。對在常規FPGA中實現異步電路帶來新的開發特性，特別對SoC的異步互聯具有較好的實用價值。
