Release Announcements in 10.2f

[nodvtid] -

In 10.3, support for Linux RHEL 4 will be discontinued.
In 10.4, support for Windows XP and Windows Vista will be discontinued.

[10.2d] OVL is upgraded to v2.8.1.
[10.2d] The VHDL OSVVM (Open Source VHDL Verification Methodology) library, sources and documentation have been updated to version 2014.01. Dependency checks in vopt and vsim will force recompilation of designs that use the osvvm library. If optimization is performed using vopt, the optimizer will automatically generate new optimized design units. Without the optimization step, vsim will detect dependency errors.
[10.2] Support for Solaris SPARC and Solaris x86 has been discontinued. All Solaris OS platforms are not supported.
[10.2] Support for RedHat Enterprise Linux (RHEL) 3.0 and Novell SUSE Linux Enterprise (SLES) 9 has been discontinued.
[10.1] Support for GCC versions gcc-4.1.2-sunos510/gcc-4.1.2-sunos510x86 has been discontinued.
[10.0] Support for Solaris 8 and Solaris 9 has been discontinued.
[nodvtid] - The 10.2g Update Release will be the last release in the 10.2 series

Compatibility Issues with Release 10.2f

SystemVerilog Compatibility

dvt65714 - (results) When "+vlog_retain_same2same_on" was specified, conditional specify paths with SDF RETAIN delays did not evaluate correctly.
dvt68824 - (results) Calling vpi_get_time function with a VPI handle of wrong type (for example to a package) would cause vsim to crash.

User Interface Defects Repaired in 10.2f

dvt38385 - In GUI mode, using the restore command outside of vsim caused uninformative error "can't read "vsimPriv(Server)": no such element in array" and would cause eventual GUI crash.
dvt69259 - In some rare cases the GUI would hang when right-clicking on a signal in the Source Window. Depending on the specific hierarchy of the design an infinite loop would occur when checking conditions to enable/disable the items in the RMB menu.
dvt38562 - The context and locals windows will sometimes stop working correctly when stopping and single stepping in code related to dynamic threads. This issue has been resolved.
dvt63858 - Toggling the "Within Cells" mode of the Memory List window while a search filter is in use can cause the display of an incomplete list of memories. This issues has been resolved.

SystemVerilog Defects Repaired in 10.2f

dvt65714 - (results) When "+vlog_retain_same2same_on" was specified, conditional specify paths with SDF RETAIN delays did not evaluate correctly.
dvt68824 - (results) Calling vpi_get_time function with a VPI handle of wrong type (for example to a package) would cause vsim to crash.
dvt68778 - Vsim would sometimes generate incorrect errors like this for code in SystemVerilog packages:
# ** Error: (vsim-3043) test.sv(-2): Unresolved reference to 'a'.
dvt65907 - Fixed a fatal error in vsim, which occurs sometimes when a module containing a for loop but works when compiled with -sv.
dvt68960 - Fixed an issue in SV bind doesn't work, when bind target lies within an generate scope which can't be elaborated during vopt.
dvt22670 - In some cases with inline randomization constraints, vlog incorrectly reported an error like:
** Error: pkg.sv(39): Can't use a typedef ('my_enum_t') here.
with the usage of a valid type name.
dvt71152 - Bit-selects and part-selects of 2-state variables in module input port connections produced incorrect results in some cases.
dvt73310 - Traversing individual words of large SV memories using vpi_iterate/vpi_scan functions caused huge memory usage.

VHDL Defects Repaired in 10.2f

dvt70898 - Use of the function rising_edge and falling_edge could, in some case, trigger an internal error
dvt72143 - If an uninstantiated package contains signal declarations, and an instance of the package is associated with an interface package in an entity, package, or subprogram instantiation, accesses to the signals could lead to simulator error messages of the form:
```
# ** INTERNAL ERROR: pkgref: export lookup failed for package #8[7]
```
dvt73051 - Fixed elaboration crash with subelement association. The formal must be an element or subelement of a multidimensional port and the actually a 2008 signal expression.
[nodvtid] - Aggregates of signals in subprograms, either as parameters to other subprogram, or as targets of signal assignments could cause a crash if the aggregate contained both parameters and non-parameter signals.
dvt74124 - Vcom could fail with an internal error when a port map statement is present on a block
dvt74313 - If an attribute that returned a range is used as the expression to a return statement, incorrect machine code could be generated. A range is not a valid return value and is now flagged as an error a compile time.
dvt71451 - Predefined attribute A'ELEMENT could not have as its prefix a function call. The LRM is not clear on this since A must be either an array type name or appropriate for an array object, and a function call is neither. But because other attributes like A'RANGE where A is a function call are handled as legal, the A'ELEMENT attribute now also allows this. Further, as a non-compliant extension of the language O'SUBTYPE may also have O be a function call.
dvt74843 - The compiler would hang if it encountered a VHDL error involving a type declaration of an array type whose element subtype is an incomplete type of the same name as the array type itself.

Mixed Language Defects Repaired in 10.2f

[nodvtid] - Hierarchical references from Verilog to fields of a VHDL record signal could cause the tool to fail.

SystemC Enhancements in 10.2f

dvt67502 - Added -gblso command option to vopt and the companion modelsim.ini variable 'GlobalSharedObjectList'
```
-gblso       Load the specified shared library with global symbol visibility.
```
This option would be required if the SystemC top is elaborated in vopt and is depending on the symbols from a common library being loaded with vsim -gblso switch.
