变量 作用 影响的命令 举例 bus_range_separator_style bus_multiple_separator_style bus_inference_descending_sort 一个port bus的成员如何排列 read(对erilog没有用) write(仅仅对vhdl) 如果bus_inference_style 设置为%s ,那么ports A A A and A 将会引入 一个叫做A的bus,而bus_inference_descending_sort 就会影响A 还是A bus_minus_style read -vhdl bus_multiple_separator_style 确定multibit cell的名字,和multibit有关 影响multibit mapping,和bus_range_separator_style, bus_naming_style有关 如果bus_range_separator_style设置为":", bus_naming_style设置为"%s ", bus_multiple_separator_style设置为",", 则cells named q ,q ,q ,q ,q ,q 将会packed into 6-bit wide cell, cell的名字就是q bus_naming_style specifies the style to use in naming and idividual port member,net member,cell instance member of and edif array, or of verilog/vhdl vector,命名bus中member read write (only edif) bus_range_separator_style 只影响edif网表 read write (only edif) bus_dimension_separator_style define_name_rules -target_bus_style bus_inference_style 如何将单个的bit into a port bus read(除了.db和vhdl) write(仅仅对vhdl) 其实就是一个模式匹配
