5. Fedora 针对特定爱好者所做的变更

5.1. 电路设计

5.1.1. gtkwave

gtkwave 由 3.3.41 更新至 3.3.51。更新包括大量的升级,其中有:
  • 为 Vermin 中的新增的结构添加更多支持。
  • 为 rtlbrowse 代码窗口增加滚轮支持。
  • 通过 vpd2vcd 增加 VPD 支持。
  • Added preliminary do-nothing generate support in vermin.
  • Added "Open Hierarchy" option that will expand the SST and select the hierarchy for a given signal selected in the Signals window.
  • Added preliminary support for FsdbReader.
  • Added generate as scope type to VCD/FST/FSDB.
  • Display signal direction column in SST if not all signals are declared as FST_VD_IMPLICIT.
  • Added extraction of in/out/inout from FSDB into FST with vcd2fst helper executable.
  • Added support for SV structures, unions, classes, packages, programs, and interfaces.
  • Preliminary support for SV datatypes of bit, logic, int, shortint, longint, byte, enum, and shortreal in VCD and FST. Added sparse array datatype to FST (currently unused by gtkwave).
  • Added support for attribute begin/end in FST. (Currently unused by gtkwave.) This allows embedding of various data inside the structure tree.
  • Added ability to store $comment in FST files via the attribute mechanism (FST_AT_MISC/FST_MT_COMMENT).
  • Added ability to store environment variable information in FST files (FST_MT_ENVVAR).
  • Added direction filters to SST name filter search. That is, adding +I+, +O+, +IO+, +B+, or +L+ before the regular expression adds additional filtering criteria. Direction filters are case-insensitive.
  • Added VHDL hierarchy types to FST, internal VCD loaders and also vcdfst/fst2vcd.
  • Added in VHDL to FST (which will also allow other languages): gtkwave can process these types (e.g., signal + std_ulogic), but there are currently no simulators supporting them.
  • 为“/文件/抓取到文件”增加 PNG 图像抓取菜单。
  • 为 FST 增加 VHDL 软件包类型。
  • Added fstWriterSetSourceStem() so writers can embed source stems in the FST file.
  • 更新了示例/gtkwaverc 加速选项,以反映 gtkwave 主窗口主菜单的当前状态。
此外,还包括大量 bug 修正以及内部改进。更多信息可参考 变更日志,或访问 http://gtkwave.sourceforge.net/

5.1.2. XCircuit

xcircuit 已更新至版本 3.7.44。3.7 版修改了选择机制,可同时顾及点和线段元素以及全部元素。这可让“编辑”功能立刻做为很多元素的拉伸功能使用。
同时还为对象增加了线宽不变的特性。可以让对象实例(比如电路符号)线宽不变,对象缩放时也不会造成线宽的变化。这样一来,在同一个图中重新调整电路符号的相对大小也不会导致针脚处线宽的间断。
其它有用的补充包括:
  • 跟踪用于路径中相邻样条的样条控制点
  • Clipmasks(形状可用于修剪其它元素的外观)
  • 多边形到曲线转换例程
  • 升/降元素的撤销/重做
  • 单步升降元素
  • 梯度场生成器---颜色梯度场由图形图像类型生成

5.2. 业余无线电

5.2.1. fldigi

fldigi 升级至 3.21.76。部分变更包括:
  • 对 ADIF 日志记录的改进
  • 更好地弱信号 MFSK
  • THOR 中的改进
  • 激活 ARQ 客户端时支持 UTF-8 显示
以及其它众多改进。

5.2.2. gnuradio

Fedora 20 采用 gnuradio 3.7.1。
主要新特性有:
New blocks include gr::analog::fast_noise_source and gr::analog::agc3_*. agc, agc2 and agc3 blocks now have a unified interface. New components gr-fec and gr-channels have been added. A new tool allows the creation of out-of-tree VOLK libraries.
http://www.gnuradio.org 介绍了这些变更的详细信息,同时提供了更详细的文档。

5.2.3. qucs

qucs 已升级至 0.0.17。关键改进有:
  • 新的 BSIM nMOS 和 pMOS 型号
  • m-code transient solver interface

5.2.4. trustedqsl

trustedqsl has been updated to 1.14.3. Updates include correcting some CQ zones, enhanced handling of duplicates, and improvements in some error messages.
详情可参考项目页面 http://sourceforge.net/projects/trustedqsl/

5.2.5. xastir

xastir 2.0.4 带来了大量的变化和性能上的改进。要了解详情请参考帮助文件或访问项目页面 http://www.xastir.org

5.2.6. xnec2c

xnec2c 已更新至 2.3。对用户来说 2.1 和 2.3 版本几乎没有显著差异,但还是在程序的内部有所表现。大多数的变更都对 nec2c 软件包有所影响,该软件包为 xnec2c 提供计算引擎。
