During the 80ies used worldwide, KARL was the leading hardware description language, trailblazer for VHDL. Being fully calculus-capable KARL and its graphic user interface supported "Structured Hardware Design" and poineered synthesis by top-down term rewriting. KARL is PASCALish. Earlier hardware languages in the 70ies were dialects of FORTRAN or APL or other old languages. The world's first complete VLSI design framework has been KARL-based (CVT and CVS projects). The KARL book was a bestseller and caused Reiner's first invitation to give a keynote speech.
