nMicrocoder is an ncurses EDA tool to write microcode. Basically, it is a stripped down spreadsheet program that lets you fill a table with "0", "1", and "-", and gives you compile-ready verilog code in return. It was written as an alternative to full spreadsheet programs. It is known to run on Linux, IRIX, and Solaris, unless ncurses 5.3 is installed.

The assembler version supports Linux, FreeBSD, OpenBSD, NetBSD, Win9x, QNX, Atheos, BeOS, ELKS, and DOS. There is also a separately distributed version written in C which supports some other Unix versions and CygWin. It is also possible to use regular expressions by using child processes like sed. e3 has a built in arithmetic calculator.
