Release Notes For ModelSim 2020.4 – Date: Oct 13 2020

SystemVerilog Defects Repaired in 2020.4
– QSIM-64132 – Vlog sometimes gave incorrect errors like:
– ** Error: while parsing file test.sv(50): Failed to find the name ‘get_type’ in scope ‘tpkg’
– For names like ‘pkg::typename::get_type() where “typename” is a typedef name resolving to a class.
– QSIM-64922 – Vlog reported the error:
– ** Error: test.sv(7) Illegal reference to an interface type C::Intf in implements clause.
– In cases where “C” was a parameterized class type and ‘Intf” was a typedef name referenceing an interface class.
VHDL Defects Repaired in 2020.4
– QSIM-65962 – During compilation with the -autoorder and -quiet switches, if semantic errors were encountered during the refresh phase, the errors would not be printed. This behavior is incorrect, and now all errors are printed, though other compilation logging messages are suppressed.
– QSIM-66278 – Large data structures that take over 2Gbytes of space would crash if default initialization is used. For this to happen the default value for all fields in the data structure must be 0 or NULL. Explicitly initializing the object will work around the issue.
– QSIM-65639 – The design.bin could have incorrect bounds on signals. This occurs if the signal bounds depend on functions calls. An these functions use the std.textio.
