This paper firstly proposed a design scheme of application specific integrated circuit(ASIC)design tools based on OpenLane.Secondly,based on Gambas development environment,plug-in tech-nology was used to integrate OpenLane toolchain,and completed OpenLane-based ASIC design tool,namely EasyASIC.The tool covers engineering management,code editing,Verilog code compilation,simulation,OpenLane initialization file configuration,GDSII file generation,GDS2D and GDS3D display to achieve ASIC design automation.Finally,taking the 32 bit signed multiplier as an example,the function verification test of this tool was carried out.The experimental results show that EasyASIC can run smoothly in the domestic Deepin operating system,and realize the transformation of 32 bit signed multiplier from register transfer level file description to GDSII file.The tool has strong operability and ease of use,and has certain reference significance for improving the development of Chinese integrated circuit design tool software industry.
