Ada is heavily used and carries a historical influence not only with embedded software space, but also with hardware space: VHDL is one of the two major hardware description languages used in ASIC design and FPGA implementations. (The other language is Verilog, based on - you guessed it - C, because of its popularity.)

"Due to the Department of Defense requiring as much of the syntax as possible to be based on Ada, in order to avoid re-inventing concepts that had already been thoroughly tested in the development of Ada, VHDL borrows heavily from the Ada programming language in both concept and syntax." - https://en.wikipedia.org/wiki/VHDL#History
