I have modeled SolarCollector(UTSC) from two month ago. because of EP
v3.1 was lanched, I changed my UTSC IDF files from v3.0 to v3.1,
but when I ran simulation, there was fatal error occured.
Of course, my UTSC IDF file is fine with v3.0.
please let me know what is the problem.
(I guess it is one of the bugs in v3.1 probably, right?)
