Great post from Liam Fraser on the Raspberry Pi Foundation blog.
RP2040 has been in development since summer 2017. Chips are extremely complicated to design. In particular, the first chip you design requires you to design several fundamental components, which you can then reuse on future chips. The engineering effort was also diverted at some points in the project (for example to focus on the Raspberry Pi 4 launch).
Once the chip architecture is specified, the next stage of the project is the design and implementation, where hardware is described using a hardware description language such as Verilog. Verilog has been around since 1984 and, along with VHDL, has been used to design most chips in existence today. So what does Verilog look like, and how does it compare to writing software?
