1. The number type in expression evaluation in expr.C was changed from int to double.
2. A memory leak in Argv::operator= was removed.
3. New int type generator parameter. This extension can cause compile errors, if the previous ArgTab_t constructor was called with a mixture of int and double arguments. The code>ArgTab_t constructor now creates a generator parameter of type double, if solely called with double arguments and a generator parameter of type int, if called solely with int arguments. The remaining behaviour of the generator argument classes is unchanged. Especially retrieval methods ArgTab_t::Value, ArgTab_t::Lower, ArgTab_t::Upper return the same result for both an int type and a double type generator parameter. Hence exisiting generators work as before and only eventual compile problems caused by argument ambiguities for the ArgTab_t constructor have to be resolved.
4. A number converter to recognize Cadence floating point syntax was added. The default real converter for generator is the existing one that understands SPICE syntax. A different real converter can be registered globally by calling the new function ArgTab_t::SetRealConverter.
5. The generator dialog now activates scrollbars if needed. This helps to write generators with many parameters.
6. The GDSII input/output drivers were made more extensible concerning the handling of MGEN hardcoded properties. This is achieved by introducing the class MgenGdsOutput that defines an interface and implements the standard functionality of the output of MGEN hardcoded properties. MgenGdsOutput is now used in MgenGdsDB to output data in GDSII format. To write a different GDSII file with an own propery semantics, a user can derive his/her own gds output class from MgenGdsOutput and overload the virtual functions PutGeoProp and PutInstProp.
7. The generator cache was enhanced by a new import callback. With the help of the import callback the generator cache can be integrated in any software. The generator cache integration in PARIS was adapted accordingly.
8. Made the library libMgenProcess shared.

MANIAC

1. Connection caching in ManiacClient was introduced. The MANIAC server was changed accordingly to handle permanent remote connections.
2. Fixed crash in NumberIterator constructor, if called with undefined Number.
3. Fixed potential crash in Number::Avg methods.
4. New method ManiacDB::GetTable(tablename, title, date, time, analysis)
5. Store signals in the MANIAC viewer and NamedVectors in the MANIAC library in a TSet to improve performance.
6. Implementaion of a measurement bar for interactive measurements in a graph.
7. Additional tabular view of signals. The tabular view corresponds to the graphical view in a regions. The measurement bar is viewed in both the graphical and the tabular view.
8. Pool allocators of Number objects to improve performance and optimize memory allocation.
9. New functionality to merge signals into existing signals.
10. New functions Number::SimpleDrv, Number::Avg2, Number::ConstSeq, Number::EqSeq.
11. New functionality ShiftBack and shiftback commands to allow for continuous monitoring of signals in a limited interval.

Release Notes for MGEN/PARIS 1.5

The following bugs reported at sourceforge.net were fixed: 1061988, 1059778, 1046578, 1042538, 1039044, 1038490, 1010627, 1001433, 988214, 964252.

The following feature requests were implemented: 647735, 652014, 1043017.

The following changes and improvements were made in MGEN/PARIS 1.5 compared to MGEN/PARIS 1.4:

General

1. Added support for the Cygwin environment. MGEN/PARIS can be compiled and run under Cygwin and thus also under Windows. The platform name for cygwin is i686-pc-cygwin.
2. There is no further need to patch the library of the GCC 3.x compiler to provide the file descriptor constructor for the fstream class. Instead new classes named fdstream were implemented that provide the required functionality.
3. Moved all Tcl/Tk applications to Tcl/Tk 8.4 and Itcl/Itk 3.2.

PARIS

1. The display of pinname has been changed. Compared to the previous version, where only view pinname on or off was possible, now there are three levels of pinname view. In level 0 no pinnames are drawn. In level 1 only pinnames of hierarchical cells are shown, but not the pinnames of leaf cells. In level 2 all pinnames are shown including the pinnames of leaf cells. The command parameters of the VIEW command and the menus have been changed accordingly.
2. The EPSOUT command got a new OFFSET switch to achieve a margin on a paper, if the eps file is printed.
3. The GDSII files written by PARIS are padded with 0 bytes to achieve a fixed record length in the GDSII file. The record length can be specified by a command argument to the GDSOUT command. The GDS export dialog was adapted accordingly.
4. The display of net lines was decoupled from the presence of net information in a cell. In version 1.4 net line display was tightly coupled with the validity of net information. In version 1.5 the net information may exist in a cell, but the net line display may be switched off. For this purpose the boolean snetFlag was changed to an integer with 3 possible values. 0 means no net information, this is identical to the previous false case. 1 means net list information is valid, but net lines are not displayed. 2 means net list information is valid and net lines are to be displayed, this is identical with the previous true case. This change implies a new revision of the PARIS data format. Hence files written with version 1.5 can't be read with older versions. The NETLIST command and the menus were extended to provide the new functionality.
5. Fixed null pointer access bug in the rpc server.
6. Fixed potential buffer overflow problems in the RPC interface.
7. Fixed memory leak and potential buffer overflow problems in createlist.C.
8. Eliminated memory leaks of XmStrings in dialog.C.
9. There should be no further endless loop of PARIS, if the terminal is stopped, in which the PARIS process runs. Especially there should be no zombie processes left after logout that use up lots of cpu resources.

MGEN

1. The new version of the libMgen2s shared library is now 1.5.
2. Complete flexelint check performed and eliminated all problems found by flexelint. This also includes 2 real bug fixes.
3. The class to handle generator argument, ArgTab_t was completely rewritten, The new implementation uses a handle/representation approach with a polymorphic class tree instead of a union to implement the different argument types. The man page was updated accordingly.
4. New argument types bool and enum. Boolean argument are presented as a check box in the generator dialog, enum arguments as an option menu. The generator protocol was extended to provide the new types.
5. According to the changes of net list information in PARIS the type of MgenDef_t::snetFlag was changed to int.
6. Similar to PARIS the GDSII write now pads the output file to fixed size records.
7. Bone variant of basic CMOS transistor generator.

MANIAC

1. The new version of the libmaniac library is now 4.3
2. Documentation completed.
3. Replaced NAG library by fftpack library for Fast Fourier Transformation subroutines. The usage of the NAG library is still possible and can be activated by compiler options.
4. Adjustable date format in date regions. Button in Options menu and dialog box to change date format provided.
5. Inserted magic string at the beginning of the binary file.
6. New procedure Number::symbols detects the symbols references in compute expressions.
7. Symbol detection in the maniac::compute command
8. Human readable date/time output in the MANIAC ASCII format in tables with analysis type DATE.
9. Functions and commands for the extraction of partial curves.
10. X-only or y-only zoom with mouse possible
11. Some minor bug fixes.

Libraries

Base Libraries

1. Incremented version of libaswbase to 1.1.
2. Inserted the usage of the macro INCLUDETEMPLATECODE in all template classes. If INCLUDETEMPLATECODE the template implementation code locate in a .C file is included additionally in the header file. This behaviour is required by some tools or compilers, that cannot find the template implementation files automatically.
3. Fixed initialization bug in copy constructor of slist_t.
4. New class StringSplitter. In constrast to StringTok StringSplitter does not overread multiple occurences of the specified delimiter character. This enables the user to tokenize a string containing empty fields.
5. New method String_t::Replace with a character set argument instead of a single character.
6. New function GetIpAddress, GetCanonicalHostname in the class SockIO.
7. New methods ISockStream::Readln/OSockStream::Writeln for line oriented reading and writing from/to sockets.
8. Additional constructor of ServerSocketIn that allows for creating a server socket allocating a port in a specified port range.
9. New classes fdstream, ifdstream, ofdstream that provide the possibility to attach a C++ stream to a file descriptor. These classes are currently only required for the library coming with gcc 3, that does not have this functionality any more. All other supported libraries have this functionality and there the fdstream classes are implemented as a typedef.
10. Fixed potential buffer overflow problem in operator(ISockStream&, String_t&).
11. Fixed potential buffer overflow problems in the ash. This implies an interface change of some ash functions accessing shell variables.

Tasks Library

1. New config file reader to read simple line oriented config file implemented by template classes.
2. Doxygen documentation completed.
3. New function Process::Exec(TVarr<String_t>&).
4. New class MTWorkQueueReq, that requeues a task at the beginning of the queue, if a task is not runnable.
