Here, we described two new endoparasitic species, N. limpopoensis n. sp. and N. zuluensis n. sp., from southern African sedges Carex spicatopaniculata Boeckeler ex C.B.Clarke and C. zuluensis C.B.Clarke, respectively, and investigated the Cox1 phylogeny of Novophytoptus. Contrary to ...
Read in physical data: SDF and parasitics This is so you can subsequently write out a partial SDF and parasitic file only for the nets and cells in the ILM Ensure you have propagated all real clocks in the design This is so that PT will keep the clock tree information in the ILM ...
