Fatal error found by spectre during AHDL read-in.
FATAL (VACOMP-2096): File '/home/meow/SMIC_018_MMRF/smic18mmrf/../models/spectre/res.def' does not appear to be a valid Verilog-A file. In previous releases, '.def' was a file extension typically used for SpectreHDL files but SpectreHDL is no longer supported. If this file is a SpectreHDL file, you need to replace it with an equivalent Verilog-A file.
