+Makerchip is a cloud based browser application developed by Redwood EDA to do digital circuit design. One can simulate Verilog/SystemVerilog/Transaction-Level Verilog code in Makerchip. eSim is interfaced with Makerchip using a Python based application called Makerchip-App which launches the Makerchip IDE.
