本资源是一份名为《Vivado Design Suite Tcl命令参考指南》(UG835 v2019.2)的手册，发布日期为2019年10月30日，涵盖了Vivado设计套件中的TCL命令集。TCL是Tool Command Language的缩写，是一种脚本语言，广泛用于与Xilinx Vivado设计工具交互，进行设计流程的自动化和定制。这份文档的重要性在于它提供了详细的命令列表和功能概述，帮助用户高效地管理和控制Vivado的设计流程。以下是一些关键的TCL命令及其功能： 1. `close_hw_manager`：用于关闭硬件管理器，可能涉及清理与硬件交互的资源。 2. `delete_qor_suggestions`：删除存储的快速优化建议，可能在优化设计后执行。 3. `get_hw_ddrmcs`：获取硬件描述文件（DDRMC）的相关信息。 4. `open_hw_manager`：打开硬件管理器，以便进行设备配置和操作。 5. `open_hw_platform`：初始化或打开硬件平台，可能涉及加载硬件描述文件。 6. `refresh_hw_ddrmc`：刷新DDRMC的状态，确保其是最新的。 7. `report_hw_ddrmc`：报告关于DDRMC的详细信息。 8. `update_sw_parameters`：更新软件参数，调整设计行为。 9. `validate_hw_platform`：验证硬件平台设置的正确性。 10. `write_hw_platform`：写入或保存硬件平台状态，可能是保存硬件配置。 11. `write_hw_platform_metadata`：写入硬件平台元数据，可能包括设计属性。新加入的2019.2版本命令包括： - `apply_bd_automation`：用于应用板级自动化脚本，简化设计流程。 - `assign_bd_address`：分配边界框模块地址，处理模块布局。 - `config_timing_analysis`：配置时序分析设置，优化设计性能。 - `connect_hw_server`：连接到硬件服务器，用于远程操作或数据交换。 - `create_bd_intf_port` 和 `create_bd_port`：创建边界框接口端口和普通端口，用于模块间通信。 - `create_ip`：导入或创建IP核心，集成外部知识产权。 - `export_as_example_design`：导出设计为示例项目，便于分享或学习。 - `get_bels`：获取可重用的逻辑块（Bel）列表，用于设计重组。 - `highlight_objects`：高亮显示设计中的特定对象，便于可视化。 - `launch_runs`：启动设计运行，执行仿真或综合任务。 - `make_bd_intf_pins_external` 和 `make_bd_pins_external`：将接口和普通端口设为外部引脚，利于信号完整性分析。 - `place_design`：放置设计元素，进行物理布局。 - `pr_recombine` 和 `pr_subdivide`：重构设计，合并或拆分模块。 - `program_hw_devices`：下载设计到硬件，执行配置。 - `read_checkpoint`：读取检查点文件，恢复设计状态。 - `read_qor_suggestions`：读取快速优化建议，用于后续设计改进。 - `report_incremental_reuse`：报告设计中重复使用的模块，优化资源利用。 - `report_ip_status`：报告IP核心的状态，如集成、配置等。 - `report_methodology`：提供设计方法论报告，可能包含最佳实践和推荐。 - `report_qor_suggestions`：再次报告快速优化建议，可能包含新版本的优化结果。 - `report_ram_utilization`：报告RAM的利用率，帮助优化内存管理。 - `synthesize_design`：执行综合任务，生成硬件描述语言代码。 - `unhighlight_objects`：取消高亮显示设计对象。 - `write_checkpoint`：写入检查点文件，保存设计状态。 - `write_ibis`：导出接口描述语言文件，用于测试或仿真。 - `write_project_tcl`：保存项目级别的TCL脚本，便于复用或共享。 - `write_qor_suggestions`：写入快速优化建议，记录优化过程。 - `wri`：可能是一个拼写错误，应该是`write_project_tcl`的一部分。这些命令覆盖了从设计导入、配置、布局到测试、优化的整个设计流程，是Vivado用户必备的参考资料。熟练掌握这些TCL命令可以显著提高设计效率和灵活性。

• get_cells * -hierarchical -filter “lib_cell == FD”

To do more elaborate string ltering, ulize the =~ operator to do string paern matching. For

example, to query all ip-op types in the design, do the following:

• get_cells * -hierarchical -filter “lib_cell =~ FD*”

Mulple lter properes can be combined with other property lters with logical OR (||) and

AND (&&) operators to make very powerful searches. To query every cell in the design that if of

any op type and has a placed locaon constraint:

• get_cells * -hierarchical -filter {lib_cell =~ FD* && loc != “”}

Note: In the example, the lter opon value was wrapped with curly braces {} instead of double quotes.

This is normal Tcl syntax that prevents command substuon by the interpreter and allows users to pass

the empty string (“”) to the loc property.

Handling Lists of Objects

Commands that return more than one object, such as get_cells or get_sites, return a

collecon in the Vivado tool that looks and behaves like a nave Tcl list. This feature allows

performance gains when handling large lists of Tcl objects without the need to use special

commands like the foreach_in_collection command. In the Vivado Design Suite

collecons can be processed like Tcl lists using built-in commands such as lsort, lsearch, and

foreach.

Typically, when you run a get_* command, the returned results are echoed to the console and

to the log le as a Tcl string, rather than as a list due to a feature of Tcl called "shimmering".

Internally, Tcl can store a variable or value both as a string and as a faster nave object such as a

oat or a list object. In Tcl, shimmering occurs when the representaon of the object or value

changes from the list object to the string object, or from string to list. A list of Vivado objects is

returned by the get_* command, but the shimmered string representaon is wrien to the log

le and Tcl console.

However, to improve performance and prevent overloading memory buers, the Vivado Design

Suite limits and truncates the shimmered string to a default character length dened by the

tcl.collectionResultDisplayLimit parameter, which has a default value of 500.

Commands that can return a signicant number of objects, such as get_cells or get_sites,

will truncate the returned string, ending it with an ellipsis ('...'). You can use the set_param

command to change the tcl.collectionResultDisplayLimit parameter value to return

more or fewer results.

CAUTION! The combinaon of shimmering and the

tcl.collectionResultDisplayLimit

parameter

prevents the use of

and

list operators in the Vivado Design Suite. Since a string shimmered from the list

may be truncated, the

and

operators cannot eecvely determine if a specied object is in, or not-in, a

list of objects. You should use list commands such as

lsearch

and

lsort

instead of

if {[lsearch -exact [get_cells *] $cellName] != -1} {...}

You can capture the complete list returned by the get_* command by assigning the results to a

Tcl variable:

set allSites [get_sites]

he actual list in the variable assignment includes the complete result set, and is not truncated by

the tcl.collectionResultDisplayLimit parameter. An example of this is seen in

hierarchically querying all the cells in a design:

%set allCells [get_cells -hierarchical]

DataIn_pad_0_i_IBUF[0]_inst DataIn_pad_0_i_IBUF[1]_inst \

DataIn_pad_0_i_IBUF[2]_inst DataIn_pad_0_i_IBUF[3]_inst \

DataIn_pad_0_i_IBUF[4]_inst ...

%llength $allCells

42244

%lindex $allCells end

wbArbEngine/s4/next_reg

In the preceding example, the result of the hierarchical get_cells command was assigned to

the $allCells variable. In appearance, the results are truncated. However, a check of the

length of the list reports more than forty thousand cell objects, and the last index in the list

returns an actual object, and not an ellipsis.

TIP: I

f necessary, you can also use the

join

command, to join the list of objects returned by the

get_*

Tcl

command, with a newline (\n), tab (\t), or a space (" "), to display the un-truncated list of objects:

join [get_parts] " "

Object Relationships

elated objects can be queried using the -of opon to the relevant get_* command. For

example, to get a list of pins connected to a cell object, do the following:

• get_pins -of [get_cells inst_1]

The following image shows object types in the Vivado tool and their relaonships, where an

arrow from one object to another object indicates that you can use the -of opon to the get_*

command to traverse logical connecvity and get Tcl references to any connected object. For

more informaon on rst class objects and their relaonships, refer to the Vivado Design Suite

Properes Reference Guide (UG912).
