新手PR求助：在astro中可以使用smic库，在ICC中引用创建则会有错误

vectorli

1、执行create_mw_lib，引用smic18的参考库，创建一个library： icc_shell> create_mw_lib -technology $techfileName -mw_reference_library $cellsLibName -bus_naming_style {[%d]} -open $libName Start to load technology file ./tf/smic18m_5lm.tf. Warning: Layer 'METAL1' has a pitch 0.56 that does not match the recommended wire-to-via pitch 0.535 or 0.485. (TFCHK-049) Warning: Layer 'METAL4' has a pitch 0.56 that does not match the recommended wire-to-via pitch 0.61 or 0.66. (TFCHK-049) Warning: Layer 'METAL3' has a pitch 0.56 that does not match the doubled pitch 1.12 or tripled pitch 1.68. (TFCHK-050) Warning: Layer 'METAL4' has a pitch 0.56 that does not match the doubled pitch 1.12 or tripled pitch 1.68. (TFCHK-050) Warning: Layer 'METAL5' has a pitch 0.95 that does not match the doubled pitch 1.12 or tripled pitch 1.68. (TFCHK-050) Technology file ./tf/smic18m_5lm.tf has been loaded successfully.

(PSYN-878) Error: No valid link library specified, please check library setup. (PSYN-958) Error: Could not read the following target libraries: your_library.db

你目前给的只是ref_lib，其实就是fram，定义外框形状之类的，给出的是physical的信息，但是包含Timing等logical的信息你并没有给，所以匹配不到。
你需要：set target_library "your_std_cell_db"
set link_library "* your_std_cell_db your_memory_db"

版主你好，我遇到了同样的问题，请问你的问题是怎么解决的？

同样的问题，解决了吗

回复 1# vectorli 题主，reference library inconsistent with main library 这个Warning问题有解决嘛？
